5-(P-tolyl)thiazolo[2,3-c][1,2,4]triazole-3-thiol CAS 500112-74-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-(P-tolyl)thiazolo[2,3-c][1,2,4]triazole-3-thiol.

5-(P-tolyl)thiazolo[2,3-c][1,2,4]triazole-3-thiol (CAS 500112-74-3), molecular formula C11H9N3S2 and molecular weight 247.34 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 5-(P-tolyl)thiazolo[2,3-c][1,2,4]triazole-3-thiol (C11H9N3S2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 247.34 g/mol, it falls into the medium-molecular-weight range. 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.
