The product we are introducing here is 2,4 - Difluorobenzoic Acid. Its CAS number is 1583 - 58 - 0. This compound is offered by factory supply with a very competitive price, which makes it an appealing choice for various industries. The chemical formula of 2,4 - Difluorobenzoic Acid is C7H4F2O2. It has a molecular weight of approximately 158.1 g/mol.
Physically, it is usually in the form of a white to off - white crystalline powder. It has a melting point in the range of 150 - 154 °C, and its boiling point is about 251.1 °C at 760 mmHg. The density of 2,4 - Difluorobenzoic Acid is around 1.443 g/cm³. It is slightly soluble in water but more soluble in common organic solvents such as ethanol, acetone, and dichloromethane.
2,4 - Difluorobenzoic Acid has a wide range of applications in different fields. In the pharmaceutical industry, it serves as a key intermediate in the synthesis of various drugs. It can be used to prepare anti - inflammatory drugs, analgesics, and some anti - cancer agents. The fluorine atoms in its structure can enhance the biological activity and metabolic stability of the final drug products.
In the field of agrochemicals, it is used in the synthesis of pesticides and herbicides. The introduction of 2,4 - Difluorobenzoic Acid can improve the efficacy and selectivity of these agrochemical products, leading to better pest control and crop protection.
It also has applications in the field of materials science. For example, it can be used in the synthesis of liquid crystal materials, which are widely used in display technologies such as LCD screens. The presence of fluorine atoms in the molecule can affect the physical properties of the liquid crystals, such as their melting point, clearing point, and dielectric anisotropy.
When using 2,4 - Difluorobenzoic Acid, it is crucial to follow proper safety procedures. Wear appropriate personal protective equipment, including safety glasses, gloves, and a lab coat. Work in a well - ventilated area or under a fume hood to avoid inhalation of dust or vapors.
In a laboratory setting, when handling it for chemical synthesis, accurately measure the required amount according to the reaction stoichiometry. It is recommended to dissolve it in a suitable organic solvent before use. For example, if using it in a reaction with an amine, first dissolve 2,4 - Difluorobenzoic Acid in dichloromethane. Then, add other reagents gradually under appropriate reaction conditions, such as temperature and pressure control.
During storage, keep it in a cool, dry place away from heat and direct sunlight. Store it in a tightly sealed container to prevent moisture and air from entering, which may cause degradation of the product.
A pharmaceutical company was developing a new anti - inflammatory drug. They used 2,4 - Difluorobenzoic Acid as an intermediate in the synthesis process. By carefully controlling the reaction conditions and purification steps, they were able to obtain a high - quality drug intermediate. After further processing and formulation, the final drug product showed excellent anti - inflammatory activity in pre - clinical trials. Compared with traditional drugs, it had fewer side effects due to the unique properties brought by the fluorine atoms in 2,4 - Difluorobenzoic Acid.
In an agrochemical research project, a team was working on developing a new herbicide. They incorporated 2,4 - Difluorobenzoic Acid into the chemical structure of the herbicide. Field tests showed that the new herbicide had a higher efficacy in controlling weeds, especially some hard - to - kill broad - leaf weeds. It also had a lower toxicity to non - target organisms, making it more environmentally friendly.
