Compared with other compounds in its class, the molecular weight of 384.89 g/mol gives 6-Chloro-3-ethylbenzo[d]thiazol-2(3H)-imine 4-methylbenzenesulfonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
6-Chloro-3-ethylbenzo[d]thiazol-2(3H)-imine 4-methylbenzenesulfonate (CAS 2034157-11-2), molecular formula C9H9ClN2SC7H8O3S and molecular weight 384.89 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, 6-Chloro-3-ethylbenzo[d]thiazol-2(3H)-imine 4-methylbenzenesulfonate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 384.89 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
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.
