Mometasone Impurity 27 CAS 201601-32-3

Description

Compared with other compounds in its class, the molecular weight of 526.64 g/mol gives Mometasone Impurity 27 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Mometasone Impurity 27 (CAS 201601-32-3), a pharmacopoeial impurity reference standard (molecular formula C29H34O7S, MW 526.64 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Mometasone Impurity 27 (C29H34O7S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 526.64 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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 Mometasone Impurity 27 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.
