4,4'-Bis(2-methylthiazol-4-yl)-1,1'-biphenyl CAS 113090-48-5 chemical structure

Description

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.

4,4'-Bis(2-methylthiazol-4-yl)-1,1'-biphenyl (CAS 113090-48-5), molecular formula C20H16N2S2 and molecular weight 348.48 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 4,4'-Bis(2-methylthiazol-4-yl)-1,1'-biphenyl (C20H16N2S2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 348.48 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
