Chemical Structure
Description
4-(4-Methylbenzoyl)-N-(tert-pentyl)-1H-pyrrole-2-carboxamide (CAS 478078-76-1) is a high-purity analytical reference standard with the molecular formula C18H22N2O2 and a molecular weight of 298.38 g/mol.
The molecular framework of 4-(4-Methylbenzoyl)-N-(tert-pentyl)-1H-pyrrole-2-carboxamide (C18H22N2O2) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), 4-(4-Methylbenzoyl)-N-(tert-pentyl)-1H-pyrrole-2-carboxamide 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.
