Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(R)-Ethyl 3-amino-4-(4-bromophenyl)butanoate hydrochloride (CAS 1257446-30-2), molecular formula C12H16BrNO2HCl and molecular weight 322.63 g/mol, is a CATO reference standard with documented purity and traceability.
(R)-Ethyl 3-amino-4-(4-bromophenyl)butanoate hydrochloride (C12H16BrNO2HCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO manufactures (R)-Ethyl 3-amino-4-(4-bromophenyl)butanoate 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.
