Chemical Structure

Penehyclidine impurity 20 CAS CATO-C4X-130420 chemical structure

Description

The occurrence of Penehyclidine impurity 20 is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Penehyclidine impurity 20 (CAS CATO-C4X-130420), a pharmacopoeial impurity reference standard (molecular formula C20H28ClNOHCl, MW 370.36 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, Penehyclidine impurity 20 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 370.36 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

CATO manufactures Penehyclidine impurity 20 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.
