Description
CATO manufactures Erythromycin-N,N-dimethyl-13C2 A 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.
CATO supplies Erythromycin-N,N-dimethyl-13C2 A (CAS 202114-52-1), a certified reference material (molecular formula C35[13C]2H67NO13, MW 735.91 g/mol) for analytical method development and quality control.
The molecular framework of Erythromycin-N,N-dimethyl-13C2 A (C35[13C]2H67NO13) is characterized by 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
