Compared with other compounds in its class, the molecular weight of 408.49 g/mol gives Methyl 3-ethyl-2-imino-2,3-dihydrobenzo[d]thiazole-6-carboxylate 4-methylbenzenesulfonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Methyl 3-ethyl-2-imino-2,3-dihydrobenzo[d]thiazole-6-carboxylate 4-methylbenzenesulfonate (CAS 2034154-17-9), molecular formula C11H12N2O2SC7H8O3S and molecular weight 408.49 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Methyl 3-ethyl-2-imino-2,3-dihydrobenzo[d]thiazole-6-carboxylate 4-methylbenzenesulfonate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 408.49 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
