Chemical Structure
Description
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.
3-Mesityl-4,5,6,7-tetrahydrobenzo[d]thiazol-3-ium perchlorate (CAS 1341774-61-5), molecular formula C16H20NSClO4 and molecular weight 357.85 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, chlorine substitution, 3-Mesityl-4,5,6,7-tetrahydrobenzo[d]thiazol-3-ium perchlorate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 357.85 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
