Chemical Structure
Description
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
Ethyl 2-(2-imino-6-sulfamoylbenzo[d]thiazol-3(2H)-yl)acetate hydrobromide (CAS 1351644-36-4), molecular formula C11H13N3O4S2HBr and molecular weight 396.27 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Ethyl 2-(2-imino-6-sulfamoylbenzo[d]thiazol-3(2H)-yl)acetate hydrobromide (C11H13N3O4S2HBr) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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. 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.
