Chemical Structure

Mesalazine Impurity 29 CAS 2437-11-8 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 198.22 g/mol gives Mesalazine Impurity 29 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Mesalazine Impurity 29 (CAS 2437-11-8) is a certified pharmaceutical impurity reference standard with the molecular formula C12H10N2O and a molecular weight of 198.22 g/mol.

Structurally, Mesalazine Impurity 29 (C12H10N2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 198.22 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.

CATO manufactures Mesalazine Impurity 29 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.
