2,5-Dichloro-N-(3-methylbenzo[d]thiazol-2(3H)-ylidene)thiophene-3-carboxamide CAS 476626-89-8

Description

2,5-Dichloro-N-(3-methylbenzo[d]thiazol-2(3H)-ylidene)thiophene-3-carboxamide (CAS 476626-89-8) is a high-purity analytical reference standard with the molecular formula C13H8Cl2N2OS2 and a molecular weight of 343.25 g/mol.

2,5-Dichloro-N-(3-methylbenzo[d]thiazol-2(3H)-ylidene)thiophene-3-carboxamide (C13H8Cl2N2OS2) 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.
