Chemical Structure

ZHC-116 Impurity 3 CAS 1256782-94-1 chemical structure

Description

The occurrence of ZHC-116 Impurity 3 is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

ZHC-116 Impurity 3 (CAS 1256782-94-1) is a certified pharmaceutical impurity reference standard with the molecular formula C21H27F3N4OHCl and a molecular weight of 444.93 g/mol.

ZHC-116 Impurity 3 (C21H27F3N4OHCl) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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 ZHC-116 Impurity 3 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.
