High Purity CAS 79-09-4 Propionic Acid Formula, Structure, Molecular Weight

Jan 21, 2026 Để lại lời nhắn

is a simple, saturated short-chain fatty acid. Basically, it has a three-carbon chain with a carboxylic acid group at one end. That straightforward structure gives it some pretty interesting properties-like being highly soluble in water and having a relatively low boiling point. Because of these features, it's actually pretty useful in a bunch of industrial applications.

High Purity CAS 79-09-4 Propionic Acid Structure

CAS 79-09-4 Propionic Acid is a short-chain carboxylic acid, which means it contains a carboxyl group (-COOH).

The carbon in the carboxyl group is connected to another carbon, and that carbon is linked to a methyl group (CH₃).

 

A central carbon atom is double-bonded to one oxygen and single-bonded to a hydroxyl group (-OH).

This carboxyl carbon is also connected to the second carbon (CH₂) of the ethyl group (CH₃CH₂-).

 

High Purity Propionic Acid's simple structure makes it easy to react with other substances, suitable for various industrial uses.
