Chemical Structure
Description
CATO supplies N-(4-fluoro-3-nitrophenyl)-2-(4-phenylpiperazin-1-yl)acetamide (CAS 720667-97-0), a certified reference material (molecular formula C18H19FN4O3, MW 358.37 g/mol) for analytical method development and quality control.
The molecular framework of N-(4-fluoro-3-nitrophenyl)-2-(4-phenylpiperazin-1-yl)acetamide (C18H19FN4O3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. 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.
As a certified reference material (CRM), N-(4-fluoro-3-nitrophenyl)-2-(4-phenylpiperazin-1-yl)acetamide 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.
