Nonadecanoic acid(CAS: 646-30-0)

Nonadecanoic acid (CAS: 646-30-0) is a colorless crystalline solid with a molecular weight of approximately 274.43 g/mol. It has a pKa of about 5.6. The acid is practically insoluble in water but soluble in organic solvents such as ethanol and acetone. It is reactive towards bases and can undergo esterification and transesterification reactions.

Nonadecanoic acid can be synthesized by hydrolysis of nonadecyl acetate. A common method involves the ester exchange reaction of acetic anhydride with 19-hydroxy stearic acid, followed by hydrolysis to obtain the carboxylic acid. The reaction is catalyzed by an acid catalyst such as sulfuric acid, and it yields a high purity product with good selectivity and yield.

Nonadecanoic acid (CAS: 646-30-0) is used in various industries. In the pharmaceutical industry, it serves as a raw material for the synthesis of certain drugs. It is also used in the polymer industry to improve the properties of plastics and resins. Additionally, it has applications in the production of sensors and semiconductors due to its specific functional groups.

When handling nonadecanoic acid (CAS: 646-30-0), it is important to wear appropriate personal protective equipment (PPE), including gloves, goggles, and a lab coat. Always work in a well-ventilated area or a fume hood to avoid inhaling the fumes. Spills should be cleaned up immediately using absorbent materials. Refer to the Safety Data Sheet (SDS) for detailed emergency procedures and storage information.
