Thiobenzoic acid, bearing the CAS number 98-91-9, is a compound that merits a closer look for anyone involved in organic chemistry and chemical manufacturing. As a fine chemical intermediate, its properties dictate its utility and handling. Typically described as a pale yellow liquid, it solidifies just below room temperature, with a reported melting point often cited around 15-18°C. This physical characteristic is important for storage and transportation considerations, especially for those looking to buy thiobenzoic acid in bulk.

The chemical behavior of Thiobenzoic Acid is largely defined by its functional groups: the benzoyl carbonyl and the thiol. The presence of the thiol (-SH) group makes it a relatively strong acid compared to its oxygen analog, benzoic acid, with a pKa around 2.5. This acidity means it can readily form thiobenzoate salts in the presence of bases. This reactivity is often exploited in synthesis, where the thiobenzoate anion can act as a nucleophile. Understanding these properties is crucial for researchers and procurement managers aiming to optimize their use of this compound.

When considering how to purchase thiobenzoic acid, understanding its stability and potential reactions is also vital. Thiobenzoic acid can undergo oxidation to form the corresponding disulfide, dibenzoyldisulfide, especially in the presence of oxidizing agents or even air over prolonged periods. This means that proper storage, often under an inert atmosphere and at cool temperatures (e.g., 2-8°C as recommended by some suppliers), is recommended to maintain its integrity and purity. This is a key consideration for any company that needs to secure a reliable CAS 98-91-9 supplier.

The physical properties, such as density (around 1.174 g/mL) and refractive index, are also important for quality control and identification purposes. For industrial users, knowing the precise specifications provided by a manufacturer helps ensure that the material received meets the requirements for their specific processes. Whether you are looking for thiobenzoic acid price for a research project or large-scale production, these detailed specifications are critical.

In conclusion, Thiobenzoic Acid (CAS 98-91-9) is a compound with distinct physical and chemical properties that make it a valuable intermediate. For those seeking to source this material, focusing on reputable manufacturers and suppliers in China who can provide detailed technical information and ensure product quality is essential for successful application in synthesis and beyond.
