Chemical Structure
Description
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, Dimethyl 5-(3-chlorophenyl)-1H,3H-pyrrolo[1,2-c]thiazole-6,7-dicarboxylate 2,2-dioxide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 383.80 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).
Dimethyl 5-(3-chlorophenyl)-1H,3H-pyrrolo[1,2-c]thiazole-6,7-dicarboxylate 2,2-dioxide (CAS 337920-86-2), molecular formula C16H14ClNO6S and molecular weight 383.80 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
