Description

Compared with other compounds in its class, the molecular weight of 331.35 g/mol gives Methyl 7-(4-methylbenzenesulfonyl)-7H-pyrrolo[2,3-d]pyrimidine-4-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Methyl 7-(4-methylbenzenesulfonyl)-7H-pyrrolo[2,3-d]pyrimidine-4-carboxylate (CAS 1261365-63-2), a certified reference material (molecular formula C15H13N3O4S, MW 331.35 g/mol) for analytical method development and quality control.

The molecular framework of Methyl 7-(4-methylbenzenesulfonyl)-7H-pyrrolo[2,3-d]pyrimidine-4-carboxylate (C15H13N3O4S) 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 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), Methyl 7-(4-methylbenzenesulfonyl)-7H-pyrrolo[2,3-d]pyrimidine-4-carboxylate 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.
