4-Methyl-1-phenylquinoline-2(1H)-thione CAS 2540-29-6

Description

The occurrence of 4-Methyl-1-phenylquinoline-2(1H)-thione is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-Methyl-1-phenylquinoline-2(1H)-thione (CAS 2540-29-6), molecular formula C16H13NS and molecular weight 251.35 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 4-Methyl-1-phenylquinoline-2(1H)-thione (C16H13NS) 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 251.35 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
