5-Bromo-1-benzothiophene-2-carboxylic acid, this is an organic compound. Its physical properties are crucial and are fundamental to many chemical applications.
First, the appearance is often white to light yellow solid powder. This color state is easy to identify. In laboratory operations and industrial production, the purity and state of the substance can be preliminarily determined according to its color and shape.
Melting point is also an important physical property. Generally speaking, the melting point of 5-bromo-1-benzothiophene-2-carboxylic acid is within a specific range, which can help determine the authenticity and purity of the substance. If the melting point deviates from the normal range, or implies that it contains impurities, it will affect its chemical properties and application effect.
In terms of solubility, it has a certain solubility in organic solvents such as dichloromethane, N, N-dimethylformamide (DMF). In dichloromethane, due to the interaction between its molecular structure and dichloromethane, it can be moderately dissolved. This solubility is extremely important in organic synthesis reactions, which is convenient for the reactants to mix evenly and promote the reaction. However, the solubility in water is very small. Due to the large proportion of hydrophobic groups in its molecular structure and the weak interaction force with water molecules, it is difficult to dissolve in water.
In addition, the compound has certain stability and can exist stably at room temperature and pressure. However, when exposed to strong oxidizing agents, strong acids, and strong bases, or chemical reactions occur, resulting in structural changes. This stability needs to be taken into account during storage and transportation, and contact with these substances should be avoided to ensure that its quality is not affected.
The physical properties of 5-bromo-1-benzothiophene-2-carboxylic acids, from appearance, melting point, solubility to stability, play a decisive role in their application in the chemical field. Chemists and engineers need to accurately grasp these properties in order to maximize their effectiveness in organic synthesis, drug development, and other fields.

The market price of 5-bromo-1-benzothiophene-2-carboxylic acid is difficult to hide. Its price often fluctuates due to many factors, just like the situation changes.
The first to bear the brunt is the production process. The preparation of this compound is complicated and diverse. If the process is exquisite and efficient, the production cost can be reduced, and the price may be easy; if the process is lame and the cost is high, the price will also be high.
Furthermore, the price of raw materials affects the whole body. The synthesis of 5-bromo-1-benzothiophene-2-carboxylic acid requires specific raw materials. The rise and fall of raw material prices directly affects the price of finished products. If raw materials are scarce, the price will soar; if raw materials are abundant, the price may be close to the people.
The balance between supply and demand in the market is also the key. If the market is hungry for this product and the supply is limited, the price will rise; if the demand is low and the supply is excessive, the price will inevitably decline.
Regional differences also have an impact. Different places have different prices due to differences in logistics, taxes, and market competition. In prosperous commercial ports, the competition is fierce, and the price may be more reasonable; in remote places, the price may be higher due to logistics costs, etc.
The quality grade also affects the price. High-quality ones, with few impurities and excellent performance, often get high prices; those with slightly inferior quality, the price is also lower.
Today, if you want to know the exact market price, you need to search for market information, carefully observe the raw material market, and study the status of supply and demand before you can get a more accurate price. However, its price is like a flowing water, changing rapidly, and you must pay attention in real time to know its dynamics.
