4,4-DImethyl-1-thioxo-4,5-dihydro-1h-[1,2]dithiolo[3,4-c]quinoline-6-carboxylic acid CAS 2096311-78-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 309.43 g/mol gives 4,4-DImethyl-1-thioxo-4,5-dihydro-1h-[1,2]dithiolo[3,4-c]quinoline-6-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4,4-DImethyl-1-thioxo-4,5-dihydro-1h-[1,2]dithiolo[3,4-c]quinoline-6-carboxylic acid (CAS 2096311-78-1) is a high-purity analytical reference standard with the molecular formula C13H11NO2S3 and a molecular weight of 309.43 g/mol.

The molecular framework of 4,4-DImethyl-1-thioxo-4,5-dihydro-1h-[1,2]dithiolo[3,4-c]quinoline-6-carboxylic acid (C13H11NO2S3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

CATO manufactures 4,4-DImethyl-1-thioxo-4,5-dihydro-1h-[1,2]dithiolo[3,4-c]quinoline-6-carboxylic acid 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.
