Chemical Structure

Azelaic acid CAS 123-99-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 188.22 g/mol gives Azelaic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Azelaic acid (CAS 123-99-9), a certified reference material (molecular formula C9H16O4, MW 188.22 g/mol) for analytical method development and quality control.

The molecular framework of Azelaic acid (C9H16O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

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 Azelaic 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.
