|(what is ?)|
Nonanoic acid, also called pelargonic acid, is an organic compound composed of a nine-carbon chain terminating in a carboxylic acid with structural formula CH3(CH2)7COOH. The esters and salts of nonanoic acid are called nonanoates. Nonanoic acid is a clear, oily liquid with an unpleasant, rancid odor. It is nearly insoluble in water, but very soluble in chloroform, ether, and hexane. It is commonly used in conjunction with glyphosate, a non-selective herbicide, for a quick burn-down effect in the control of weeds in turfgrass.
Occurrence and uses
Potential pharmacological effects
Nonanoic acid may be more potent than valproic acid in treating seizures. Moreover, in contrast to valproic acid, nonanoic acid exhibited no effect on HDAC inhibition, suggesting that it is unlikely to show HDAC inhibition-related teratogenicity.
