Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Lapatinib-d7 Ditosylate (CAS 1009307-24-7), molecular formula C29H19D7ClFN4O4SC7H8O3S and molecular weight 760.30 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Lapatinib-d7 Ditosylate (C29H19D7ClFN4O4SC7H8O3S) is characterized by deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. 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 Lapatinib-d7 Ditosylate 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.
