Malonic acid - Wikipedia

Malonic acid (IUPAC systematic name: propanedioic acid) is a dicarboxylic acid with structure CH 2 (COOH) 2. The ionized form of malonic acid, as well as its esters and salts, are known as malonates. For example, diethyl malonate is malonic acid's diethyl ester. The name originates from the Greek word μᾶλον (malon) meaning 'apple'.

This Standard Reference Material (SRM) consists of a solution of organic acids (citric acid, malic acid, quinic acid, shikimic acid, and tartaric acid) in water. SRM 3286 is intended primarily for use in calibration of instruments and techniques used for the determination of these organic acids.

Maleic anhydride - Wikipedia

Maleic anhydride is a low hazard profile chemical. Maleic anhydride rapidly hydrolyzes to form maleic acid in the presence of water and hence environmental exposures to maleic anhydride itself are unlikely. Maleic acid is biodegradable under aerobic conditions in sewage sludge as well as in soil and water.
