CAS 638-08-4

Stearic anhydride

Description:

Stearic anhydride, with the CAS number 638-08-4, is a chemical compound derived from stearic acid, a saturated fatty acid. It is characterized by its white, waxy solid appearance at room temperature and has a relatively high melting point. Stearic anhydride is primarily used as a reagent in organic synthesis and as a coupling agent in various applications, including the production of surfactants, lubricants, and emulsifiers. It is known for its ability to form stable emulsions and can act as a plasticizer in polymers. The compound is generally insoluble in water but soluble in organic solvents such as ethanol and chloroform. Stearic anhydride can undergo hydrolysis in the presence of moisture, reverting to stearic acid. Safety considerations include handling it with care, as it may cause skin and eye irritation. Proper storage in a cool, dry place is recommended to maintain its stability and prevent degradation.

Stearic anhydride

CAS: 638-08-4

Stearic anhydride is a fatty acid that reacts with dextran sulfate to form a biocompatible polymer. Reactive stearic anhydride can cause hemolytic activity in the presence of cationic surfactant and at phase transition temperature. When heated, it undergoes a phase transition from the metastable form to the thermodynamically stable form. Stearic anhydride has been used as a natural compound for the production of carboxylates and acyl chains. It can also be used as a precursor in the synthesis of hydrochloric acid or magnetic particles, which are made by reacting stearic anhydride with hydrochloric acid or iron chloride respectively. Stearic anhydride is created by condensation of two molecules of stearin, but it can also be synthesized using hydroxyl groups, carboxylate groups, and acyl chains. This compound has a covalent linkage with another molecule
