Paricalcitol Impurity 18 CAS CATO-C4X-138718

Description

Compared with other compounds in its class, the molecular weight of 522.99 g/mol gives Paricalcitol Impurity 18 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

As a process- or degradation-related impurity, Paricalcitol Impurity 18 (CAS CATO-C4X-138718, C31H62O2Si2) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Paricalcitol Impurity 18 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 522.99 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 Paricalcitol Impurity 18 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.
