Chemical Structure
Description
The occurrence of Dimethyl 5-(4-(tert-butyl)phenyl)-1H,3H-pyrrolo[1,2-c]thiazole-6,7-dicarboxylate 2-oxide is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Dimethyl 5-(4-(tert-butyl)phenyl)-1H,3H-pyrrolo[1,2-c]thiazole-6,7-dicarboxylate 2-oxide (CAS 337920-87-3), molecular formula C20H23NO5S and molecular weight 389.47 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Dimethyl 5-(4-(tert-butyl)phenyl)-1H,3H-pyrrolo[1,2-c]thiazole-6,7-dicarboxylate 2-oxide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 389.47 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
As a certified reference material (CRM), Dimethyl 5-(4-(tert-butyl)phenyl)-1H,3H-pyrrolo[1,2-c]thiazole-6,7-dicarboxylate 2-oxide 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.
