Chemical Structure

Ethyl 2-methyl-4,5-diphenyl-1H-pyrrole-3-carboxylate CAS 3274-64-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 2-methyl-4,5-diphenyl-1H-pyrrole-3-carboxylate.

CATO supplies Ethyl 2-methyl-4,5-diphenyl-1H-pyrrole-3-carboxylate (CAS 3274-64-4), a certified reference material (molecular formula C20H19NO2, MW 305.37 g/mol) for analytical method development and quality control.

The molecular framework of Ethyl 2-methyl-4,5-diphenyl-1H-pyrrole-3-carboxylate (C20H19NO2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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).

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), Ethyl 2-methyl-4,5-diphenyl-1H-pyrrole-3-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.
