The synthesis method of 4-methylthiophene-2-formaldehyde has been explored by many talents throughout the ages, and today I will describe it in detail.
First, thiophene is used as the initial raw material. First, thiophene and methylation reagents, such as iodomethane, are introduced into the methyl group at the 4th position of the thiophene ring under the action of appropriate catalysts. 4-methylthiophene-2-formaldehyde can be obtained by hydroformylation of 4-methylthiophene with carbon monoxide, hydrogen chloride, etc., in the presence of palladium and other catalysts and suitable ligands. This path step is relatively clear, but the reaction conditions may be relatively strict, and the requirements for catalysts are quite high.
Second, you can start from 2-acetylthiophene. The reduction reaction of 2-acetylthiophene converts the acetyl group into hydroxymethyl group, and the commonly used reducing agent is sodium borohydride. Subsequently, the hydroxymethyl group is oxidized, and the hydroxymethyl group is oxidized to an aldehyde group with a suitable oxidizing agent, such as manganese dioxide, etc., to obtain the target product 4-methylthiophene-2-formaldehyde. This method is relatively simple to operate, but the yield control of each step of the reaction needs to be carefully controlled.
Third, there are also those who use thiophene-2-formaldehyde as the starting material. First, methyl is added to the 4-position of the thiophene ring by methylation. This methylation process requires the selection of appropriate bases and methylating reagents, and the reaction conditions also need to be carefully regulated to effectively prepare 4-methylthiophene-2-formaldehyde. The starting materials of this route are relatively easy to obtain, but the control of reaction selectivity is the key.
All these synthesis methods have advantages and disadvantages. They need to be selected according to the actual situation, such as the availability of raw materials, cost considerations, product purity requirements, and many other factors, in order to achieve the best synthesis effect.

The price of 4-methylthiophene-2-formaldehyde in the market is difficult to determine quickly. The price of the cover often changes due to many reasons, among which the price of raw materials, the complexity of the manufacturing process, the amount of market demand, and the delay in supply and transportation are all important factors.
If in the past, if the price of raw materials rose, the cost of the production also rose, and the price rose; while the price of raw materials fell, the cost fell, the price or lower. The more complex the manufacturing process, the more manpower and material resources required, and the price also rose; otherwise, it may be low. If the market is prosperous, the supply is in short supply, and the price often rises; if the demand is small and the supply is large, the price is easy to drop. If the supply and transportation are smooth, the goods can reach the market quickly, and the price may be stable; if it is blocked, the price may change due to factors.
Looking at the example of "Tiangong Kaiwu", the production system of the things described in the book also varies according to the region, season, supply and demand. 4-Methylthiophene-2-formaldehyde is the same as this, at the market price, it is often changed. In the past, there may have been a few yuan per gram, or tens of yuan. However, the current price needs to be carefully inspected by the market situation and asked by the supplier before a more accurate number can be obtained. To know the real-time price, it is advisable to study it carefully on the chemical raw material trading platform and the industry information office, so as to get a price close to the actual situation.
