Chemical Structure
Description
H-Val-p-nitrobenzyl ester · HBr (CAS 6015-79-8), molecular formula C12H16N2O4HBr and molecular weight 333.18 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of H-Val-p-nitrobenzyl ester · HBr (C12H16N2O4HBr) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine 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).
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 H-Val-p-nitrobenzyl ester · HBr 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.
