Description
CATO supplies Clarithromycin-13C-d3 (CAS 81103-11-9(unlabelled)), a certified reference material (molecular formula C37[13C]H66D3NO13, MW 751.97 g/mol) for analytical method development and quality control.
The molecular framework of Clarithromycin-13C-d3 (C37[13C]H66D3NO13) is characterized by deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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 Clarithromycin-13C-d3 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.
