Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Dimethyl 5-(2,5-dimethyl-1H-pyrrol-1-yl)-3-(2-methoxy-2-oxoethyl)thiophene-2,4-dicarboxylate.
CATO supplies Dimethyl 5-(2,5-dimethyl-1H-pyrrol-1-yl)-3-(2-methoxy-2-oxoethyl)thiophene-2,4-dicarboxylate (CAS 339020-23-4), a certified reference material (molecular formula C17H19NO6S, MW 365.40 g/mol) for analytical method development and quality control.
The molecular framework of Dimethyl 5-(2,5-dimethyl-1H-pyrrol-1-yl)-3-(2-methoxy-2-oxoethyl)thiophene-2,4-dicarboxylate (C17H19NO6S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Dimethyl 5-(2,5-dimethyl-1H-pyrrol-1-yl)-3-(2-methoxy-2-oxoethyl)thiophene-2,4-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.
