Chemical Structure
Description
CATO supplies Ethyl (E)-3-(1-methyl-4-(4-methylbenzoyl)-1H-pyrrol-2-yl)acrylate (CAS 428872-08-6), a certified reference material (molecular formula C18H19NO3, MW 297.35 g/mol) for analytical method development and quality control.
The molecular framework of Ethyl (E)-3-(1-methyl-4-(4-methylbenzoyl)-1H-pyrrol-2-yl)acrylate (C18H19NO3) 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).
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), Ethyl (E)-3-(1-methyl-4-(4-methylbenzoyl)-1H-pyrrol-2-yl)acrylate 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.
