Description
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 supplies Dimethyl 2-(6-ethoxy-2,2-dimethyl-3-thioxo-2,3-dihydroquinolin-4(1h)-ylidene)-1,3-dithiole-4,5-dicarboxylate (CAS 296272-53-2), a certified reference material (molecular formula C20H21NO5S3, MW 451.58 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Dimethyl 2-(6-ethoxy-2,2-dimethyl-3-thioxo-2,3-dihydroquinolin-4(1h)-ylidene)-1,3-dithiole-4,5-dicarboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 451.58 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), Dimethyl 2-(6-ethoxy-2,2-dimethyl-3-thioxo-2,3-dihydroquinolin-4(1h)-ylidene)-1,3-dithiole-4,5-dicarboxylate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
