Chemical Structure
Description
(S)-METHYL 2-AMINO-4-BROMOBUTANOATE HBR (CAS 177325-78-9), molecular formula C5H10BrNO2HBr and molecular weight 276.96 g/mol, is a CATO reference standard with documented purity and traceability.
(S)-METHYL 2-AMINO-4-BROMOBUTANOATE HBR (C5H10BrNO2HBr) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), (S)-METHYL 2-AMINO-4-BROMOBUTANOATE HBR meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
