2,3,5-Tricarboxycyclopentane-1-acetic acid

Basic Product Information Table

1.nature

2,3,5-tricarboxyl cyclopentane acetic acid (CAS 24434-90-0) is an alicyclic polycarboxylic acid compound. Its molecular structure contains a cyclopentane skeleton, three carboxyl groups (-COOH) and an acetic acid side chain (-CHCOOH), totaling four acidic functional groups. The compound has the following notable properties:

strong acidity: Because the molecule contains four carboxyl groups, the acidity is strong (pKa ≈ 3.90), it can form a variety of salt compounds, with multidentate coordination ability, and can form stable coordination complexes with a variety of metal ions.

Good polarity and solubility: soluble in water, methanol, ethanol and other polar solvents, slightly soluble in non-polar organic solvents, intermolecular can form a hydrogen bond network.

Thermal stability: melting point is about 225 ℃, but decarboxylation reaction may occur under high temperature conditions, and the thermal decomposition temperature is higher.

Reactivity: The four carboxyl groups can independently or synergistically participate in various organic reactions such as esterification, amidation, polymerization, and crosslinking. They are important intermediates for the synthesis of polymer materials and fine chemicals.

Hygroscopicity: The product has a certain degree of hygroscopicity and needs to be sealed in a dry environment to maintain chemical stability.
