Description

Compared with other compounds in its class, the molecular weight of 327.38 g/mol gives N-(7-Methylbenzo[1,2-d:3,4-d']bis(thiazole)-2-yl)pyrazine-2-carboxamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

N-(7-Methylbenzo[1,2-d:3,4-d']bis(thiazole)-2-yl)pyrazine-2-carboxamide (CAS 1206989-34-5) is a high-purity analytical reference standard with the molecular formula C14H9N5OS2 and a molecular weight of 327.38 g/mol.

The molecular framework of N-(7-Methylbenzo[1,2-d:3,4-d']bis(thiazole)-2-yl)pyrazine-2-carboxamide (C14H9N5OS2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

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.
