N-(4,5-Dichlorobenzo[d]thiazol-2-yl)benzo[d]thiazole-2-carboxamide CAS 905678-77-5

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-(4,5-Dichlorobenzo[d]thiazol-2-yl)benzo[d]thiazole-2-carboxamide (CAS 905678-77-5) is a high-purity analytical reference standard with the molecular formula C15H7Cl2N3OS2 and a molecular weight of 380.27 g/mol.

Based on its molecular formula C15H7Cl2N3OS2, N-(4,5-Dichlorobenzo[d]thiazol-2-yl)benzo[d]thiazole-2-carboxamide contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 380.27 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
