N-(4-(Benzo[d]thiazol-2-yl)thiazol-2-yl)-2,5-dichlorothiophene-3-carboxamide (CAS 477535-91-4), molecular formula C15H7Cl2N3OS3 and molecular weight 412.34 g/mol, is a CATO reference standard with documented purity and traceability.
N-(4-(Benzo[d]thiazol-2-yl)thiazol-2-yl)-2,5-dichlorothiophene-3-carboxamide (C15H7Cl2N3OS3) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
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.
