CATO supplies N-Boc-4-amino-2-chlorobenzoic acid (CAS 232275-73-9), a certified reference material (molecular formula C12H14ClNO4, MW 271.70 g/mol) for analytical method development and quality control.
N-Boc-4-amino-2-chlorobenzoic acid (C12H14ClNO4) contains a nitrogen-containing heterocyclic scaffold, 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. 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.
