Chemical Structure
Description
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.
N-(Benzo[d]thiazol-6-yl)-5-chlorothiophene-2-carboxamide (CAS 899732-66-2) is a high-purity analytical reference standard with the molecular formula C12H7ClN2OS2 and a molecular weight of 294.78 g/mol.
N-(Benzo[d]thiazol-6-yl)-5-chlorothiophene-2-carboxamide (C12H7ClN2OS2) 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. 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.
