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-(4-((2-phenyl-5-tosylpyrimidin-4-yl)oxy)phenyl)acetamide.
CATO supplies N-(4-((2-phenyl-5-tosylpyrimidin-4-yl)oxy)phenyl)acetamide (CAS 478247-36-8), a certified reference material (molecular formula C25H21N3O4S, MW 459.52 g/mol) for analytical method development and quality control.
N-(4-((2-phenyl-5-tosylpyrimidin-4-yl)oxy)phenyl)acetamide (C25H21N3O4S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), N-(4-((2-phenyl-5-tosylpyrimidin-4-yl)oxy)phenyl)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.
