Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(5,6-Dimethyl-1H-benzo[d]imidazol-2-yl)thiazole.
4-(5,6-Dimethyl-1H-benzo[d]imidazol-2-yl)thiazole (CAS 91843-61-7), molecular formula C12H11N3S and molecular weight 229.30 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4-(5,6-Dimethyl-1H-benzo[d]imidazol-2-yl)thiazole (C12H11N3S) 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 229.30 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.
