Tamoxifen Impurity 27 CAS CATO-C4X-123327

Description

The occurrence of Tamoxifen Impurity 27 is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Tamoxifen Impurity 27 (CAS CATO-C4X-123327), a pharmacopoeial impurity reference standard (molecular formula C21H29N2O2HO, MW 358.48 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Tamoxifen Impurity 27 (C21H29N2O2HO) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 358.48 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 Tamoxifen 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.
