Ilaprazole impurity 185 CAS CATO-C4X-1130185

Description

Compared with other compounds in its class, the molecular weight of 181.21 g/mol gives Ilaprazole impurity 185 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Ilaprazole impurity 185 (CAS CATO-C4X-1130185) is a certified pharmaceutical impurity reference standard with the molecular formula C7H7N3OS and a molecular weight of 181.21 g/mol.

Owing to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system, Ilaprazole impurity 185 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 181.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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 Ilaprazole impurity 185 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.
