Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 152.67 g/mol gives Clavulanic acid Impurity 14 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
As a process- or degradation-related impurity, Clavulanic acid Impurity 14 (CAS 20485-44-3, C6H16N2HCl) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Owing to chlorine substitution, Clavulanic acid Impurity 14 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 152.67 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 Clavulanic acid Impurity 14 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.
