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-(2-oxo-6-phenyl-2H-pyran-3-yl)benzamide.
CATO supplies N-(2-oxo-6-phenyl-2H-pyran-3-yl)benzamide (CAS 21316-75-6), a certified reference material (molecular formula C18H13NO3, MW 291.30 g/mol) for analytical method development and quality control.
The molecular framework of N-(2-oxo-6-phenyl-2H-pyran-3-yl)benzamide (C18H13NO3) 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), N-(2-oxo-6-phenyl-2H-pyran-3-yl)benzamide 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.
