Comanic Acid CAS 499-05-8 chemical structure

Description

CATO manufactures Comanic 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.

Comanic Acid (CAS 499-05-8) is a high-purity analytical reference standard with the molecular formula C6H4O4 and a molecular weight of 140.09 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, Comanic Acid is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 140.09 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.
