Description
CATO manufactures 1-Ethyl-6-methoxyquinoline-2(1H)-thione 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.
1-Ethyl-6-methoxyquinoline-2(1H)-thione (CAS 4800-53-7), molecular formula C12H13NOS and molecular weight 219.30 g/mol, is a CATO reference standard with documented purity and traceability.
1-Ethyl-6-methoxyquinoline-2(1H)-thione (C12H13NOS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. 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.
