Chemical Structure

6-Ethoxy-3-methylquinoline-2-thiol CAS 917746-89-5 chemical structure

Description

The occurrence of 6-Ethoxy-3-methylquinoline-2-thiol is closely related to a nitrogen-containing heterocyclic scaffold, 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.

6-Ethoxy-3-methylquinoline-2-thiol (CAS 917746-89-5) is a high-purity analytical reference standard with the molecular formula C12H13NOS and a molecular weight of 219.30 g/mol.

Structurally, 6-Ethoxy-3-methylquinoline-2-thiol (C12H13NOS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 219.30 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.
