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 N-(9-Ethyl-9H-carbazol-3-yl)-2-(4-methyl-2,5-dioxo-4-(p-tolyl)imidazolidin-1-yl)acetamide.
N-(9-Ethyl-9H-carbazol-3-yl)-2-(4-methyl-2,5-dioxo-4-(p-tolyl)imidazolidin-1-yl)acetamide (CAS 956357-71-4) is a high-purity analytical reference standard with the molecular formula C27H26N4O3 and a molecular weight of 454.52 g/mol.
The molecular framework of N-(9-Ethyl-9H-carbazol-3-yl)-2-(4-methyl-2,5-dioxo-4-(p-tolyl)imidazolidin-1-yl)acetamide (C27H26N4O3) 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 the protonation state of its nitrogen-containing groups, 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.
