Chemical Structure
Description
O-(2-Nitrobenzyl)-L-tyrosine Hydrochloride (CAS 207727-86-4), molecular formula C16H16N2O5HCl and molecular weight 352.77 g/mol, is a CATO reference standard with documented purity and traceability.
O-(2-Nitrobenzyl)-L-tyrosine Hydrochloride (C16H16N2O5HCl) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 O-(2-Nitrobenzyl)-L-tyrosine Hydrochloride 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.
