Ornidazole Impurity 77 HCI CAS CATO-C4X-1331103

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ornidazole Impurity 77 HCI.

Ornidazole Impurity 77 HCI (CAS CATO-C4X-1331103) is a certified pharmaceutical impurity reference standard with the molecular formula C7H12N3O7PHCl and a molecular weight of 317.62 g/mol.

Owing to a carbohydrate-derived structure, an amide group, a phosphate ester group, chlorine substitution, Ornidazole Impurity 77 HCI is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 317.62 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 Ornidazole Impurity 77 HCI 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.
