Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 429.51 g/mol gives Denosumab distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Denosumab (CAS 615258-40-7), molecular formula C27H27NO4 and molecular weight 429.51 g/mol, is a CATO reference standard with documented purity and traceability.
Denosumab (C27H27NO4) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Denosumab 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.
