Chemical Structure

N-Methyl-2,3-diphenyl-1,2,4-thiadiazol-5(2H)-imine CAS 70375-43-8 chemical structure

Description

Structurally, N-Methyl-2,3-diphenyl-1,2,4-thiadiazol-5(2H)-imine (C15H13N3S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 267.35 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO supplies N-Methyl-2,3-diphenyl-1,2,4-thiadiazol-5(2H)-imine (CAS 70375-43-8), a certified reference material (molecular formula C15H13N3S, MW 267.35 g/mol) for analytical method development and quality control.

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.
