Itaconic Acid (CAS 97-65-4): Comprehensive Technical Guide
Table of Contents
1. Technical Specifications & Comparative Analysis
| Parameter | Itaconic Acid | Similar Organic Acids |
|---|---|---|
| CAS Number | 97-65-4 | N/A |
| Molecular Formula | C5H6O4 | C4H6O4 (Maleic Acid) |
| Melting Point | 165-168°C | 135°C (Citric Acid) |
| Solubility | Soluble in ethanol, acetone; Limited in water | Highly water-soluble (Acetic Acid) |
Key differentiators: Superior thermal stability (decomposition point >300°C) and dual carboxyl groups enable unique polymerization capabilities compared to conventional dicarboxylic acids.
