Chemical Structure

Poly(itaconic acid) CAS 25119-64-6 chemical structure

Description

Poly(itaconic acid) (CAS 25119-64-6), molecular formula C5H6O4 and molecular weight 130.10 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carbohydrate-derived structure, Poly(itaconic acid) is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 130.10 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures Poly(itaconic acid) under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
