1-(4-Methyl-2-(phenylthio)quinolin-3-yl)ethan-1-one CAS 400076-25-7 chemical structure

Description

The occurrence of 1-(4-Methyl-2-(phenylthio)quinolin-3-yl)ethan-1-one is closely related to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-(4-Methyl-2-(phenylthio)quinolin-3-yl)ethan-1-one (CAS 400076-25-7), molecular formula C18H15NOS and molecular weight 293.38 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 1-(4-Methyl-2-(phenylthio)quinolin-3-yl)ethan-1-one (C18H15NOS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 293.38 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
