11,12-Methyleneoctadecanoic acid

Description:

11,12-Methyleneoctadecanoic acid, also known as 11,12-methylene stearic acid, is a fatty acid characterized by a long hydrocarbon chain with a double bond between the 11th and 12th carbon atoms. This unsaturated fatty acid is derived from the natural fatty acid stearic acid, which consists of 18 carbon atoms. The presence of the methylene group introduces a unique structural feature that can influence its physical and chemical properties, such as melting point, solubility, and reactivity. Typically, unsaturated fatty acids like this one exhibit lower melting points compared to their saturated counterparts due to the presence of double bonds, which disrupt the packing of molecules in the solid state. 11,12-Methyleneoctadecanoic acid may be found in various natural sources and can be utilized in biochemical research, as well as in the synthesis of surfactants, emulsifiers, and other industrial applications. Its CAS number, 503-06-0, serves as a unique identifier for regulatory and safety purposes in chemical databases.

Phytomonic Acid

CAS: 503-06-0

Phytomonic acid, a saturated fatty acid with a cyclopropane ring structure that behaves similarly to a double bond, predominates in gram-negative bacteria L. arabinosus, protozoa, and the seed oil of B. coccineus (Connaraceae). This compound may play a role in regulating cell membrane fluidity.
