1-Isopentyl-3-(1-(4-methoxyphenyl)-5-oxopyrrolidin-3-yl)urea CAS 877640-31-8 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 1-Isopentyl-3-(1-(4-methoxyphenyl)-5-oxopyrrolidin-3-yl)urea.

1-Isopentyl-3-(1-(4-methoxyphenyl)-5-oxopyrrolidin-3-yl)urea (CAS 877640-31-8), molecular formula C17H25N3O3 and molecular weight 319.40 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1-Isopentyl-3-(1-(4-methoxyphenyl)-5-oxopyrrolidin-3-yl)urea (C17H25N3O3) 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. 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), 1-Isopentyl-3-(1-(4-methoxyphenyl)-5-oxopyrrolidin-3-yl)urea 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.
