2- (3-pyridyl) ethanol, it is mild in nature and has the characteristics of alcohols. In terms of its structure, it contains alcoholic hydroxyl groups and has the general properties of alcohols. It can be replaced with active metals such as sodium, sodium glycol and hydrogen. And because it is adjacent to the pyridyl group, the pyridyl ring has certain aromatic and basic properties, so the substance may be affected by it, and it has unique characteristics in terms of reactivity and solubility. In organic solvents, it may have good solubility, and due to the electronic effect of the pyridyl ring, the acidity of the hydroxyl group may change subtly.
3- (2-furyl) pyridine, the furyl group is connected to the pyridine ring, and the structure is unique. The pyridine ring is basic, and the furyl group is aromatic, and the two are connected, so that the substance has both partial properties. Its chemical activity is affected by the interaction of two-ring electron clouds, which can occur electrophilic substitution reaction, and it may have special spectral properties due to the conjugation effect of two rings. In terms of physical properties, its melting point, solubility, etc. may be different from general aromatic compounds. Due to the intermolecular force, it can exhibit specific dissolution behavior in appropriate solvents.
Due to their unique structures, both of them have potential applications in organic synthesis, medicinal chemistry, and other fields. With their characteristics, they may provide opportunities for the creation of new compounds and the development of new drugs.

2-% (3-pyridyl) ethanol, its chemical properties are as follows: This compound contains a structural fragment of ethanol and has the general properties of alcohols. Hydroxyl groups can undergo substitution reactions, such as reacting with hydrohalic acids, where the hydroxyl groups are replaced by halogen atoms; esterification reactions occur with carboxylic acids catalyzed by concentrated sulfuric acid and heated to form esters and water. Due to the presence of pyridine groups, the activity of hydroxyl groups may be changed due to the electron-absorbing effect of pyridine rings. Pyridine is basically basic, and the compound may also have certain alkalinity and can react with acids to form salts.
3- (2-furyl) pyridine, the pyridine ring is connected to the furan ring, and the pyridine ring is stable in nature and can undergo electrophilic substitution reaction. Due to the electronegativity of nitrogen atoms, the substitution reaction mainly occurs at the β position of the pyridine ring. Furan rings are aromatic, but more active than benzene rings, and can undergo electrophilic substitution. The activity is higher than that of pyridine rings, and electrophilic substitution reactions such as halogenation, nitrification, and sulfonation are common. In addition, the two have certain flammability due to the presence of elements such as carbon, hydrogen, and nitrogen oxides, and can be burned to form carbon dioxide, water, and nitrogen oxides under sufficient oxygen

To prepare 2 - (3 - cyano) ethanol and 3 - (2 - hydroxyethyl) cyanogen, the synthesis method is as follows:
** to prepare 2 - (3 - cyano) ethanol **:
Acrylonitrile can be taken first and reacted with ethylene oxide under the action of an appropriate catalyst. Cover acrylonitrile has unsaturated bonds, and ethylene oxide also has an active ternary ring structure. Under suitable temperature and pressure conditions, the nucleophilic addition reaction occurs between the two. The oxygen atom of ethylene oxide is nucleophilic, attacking the beta-carbon atom of acrylonitrile, causing the ternary ring to open, and then generating 2 - (3 - cyano) ethanol. The reaction formula is: $CH_2 = CHCN + C_2H_4O\ stackrel {catalyst} {\ longrightarrow} NCCH_2CH_2CH_2OH $.
can be prepared by the reaction of 3-bromopropionitrile with sodium ethanol. The bromine atom activity of 3-bromopropionitrile is quite high, and the ethoxy negative ion in sodium ethanol is a nucleophilic reagent. When the two meet, a nucleophilic substitution reaction occurs, and the bromine ion leaves to form the target product 2 - (3 -cyano) ethanol. The reaction formula is: $NCCH_2CH_2CH_2Br + C_2H_5ONa\ longrightarrow NCCH_2CH_2CH_2OH + C_2H_5OBr $. < Br >
** Preparation of 3- (2-hydroxyethyl) cyanogen **:
Reacts 2-chloroethanol with sodium cyanide. The chlorine atom of 2-chloroethanol is easily replaced, and the cyanoanion in sodium cyanide has strong nucleophilicity. The two react in suitable solvents (such as DMF, etc.), and the chlorine atom is replaced by cyanide to obtain 3- (2-hydroxyethyl) cyanogen. The reaction formula is: $ClCH_2CH_2OH + NaCN\ stackrel {DMF} {\ longrightarrow} NCCH_2CH_2OH + NaCl $.
2-hydroxyethylamine can also be reacted with formic acid to form formamide derivatives, and then dehydrated to form 3- (2-hydroxyethyl) cyanide. First, 2-hydroxyethylamine is acylated with formic acid: $H_2NCH_2CH_2OH + HCOOH\ longrightarrow HCONHCH_2CH_2OH + H_2O $, and then treated with a dehydrating agent such as phosphorus pentoxide to dehydrate it to form the target product: $HCONHCH_2CH_2OH\ stackrel {P_2O_5} {\ longrightarrow} NCCH_2CH_2OH + H_2O $.

2-% (3-pyridyl) ethanol, 3- (2-furyl) pyridine in storage and transportation, need to pay attention to many key matters.
First, the storage environment should be careful. Both are organic compounds that are extremely sensitive to temperature and humidity. It should be stored in a dry, cool and well-ventilated place to prevent chemical reactions caused by excessive temperature, deterioration, or moisture due to excessive humidity, which affects the quality. And it must be kept away from fire and heat sources. Because of its flammability, if it encounters an open flame, it is easy to cause fire and endanger safety.
Second, the packaging must be tight. Appropriate packaging materials should be used to ensure sealing to prevent leakage. Packaging materials should be resistant to chemical corrosion to avoid reactions with compounds and affect their stability. Good packaging can not only prevent the loss of substances, but also avoid pollution to the surrounding environment.
Third, the transportation process should not be ignored. When transporting, relevant regulations should be strictly followed, and transportation enterprises and tools with corresponding qualifications should be selected. During transportation, it is necessary to ensure stability, avoid violent vibration and collision, and prevent package damage. And transportation vehicles should be equipped with necessary fire equipment and emergency equipment in order to deal with emergencies.
Fourth, personnel operation also needs to be standardized. Whether it is handling, stacking, or loading and unloading during transportation, operators should be professionally trained and familiar with compound characteristics and safety operating procedures. When operating, wear appropriate protective equipment, such as gloves, protective glasses, etc., to prevent contact with skin and eyes and ensure personal safety.
