Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4’-Epi Lamivudine-15N2,13C (CAS 1246815-07-5), molecular formula C7[13C]H11N[15N]2O3S and molecular weight 232.24 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4’-Epi Lamivudine-15N2,13C (C7[13C]H11N[15N]2O3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures 4’-Epi Lamivudine-15N2,13C 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.
