4-Methylquinoline-2-thiol CAS 4437-65-4 chemical structure

Description

CATO manufactures 4-Methylquinoline-2-thiol under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

4-Methylquinoline-2-thiol (CAS 4437-65-4), molecular formula C10H9NS and molecular weight 175.25 g/mol, is a CATO reference standard with documented purity and traceability.

4-Methylquinoline-2-thiol (C10H9NS) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
