Description

CATO supplies 2-(Methacryloyloxy)ethyl 6-amino-4-(3-chloro-4-nitrophenyl)-5-cyano-2-methyl-4H-pyran-3-carboxylate (CAS 939893-89-7), a certified reference material (molecular formula C20H18ClN3O7, MW 447.83 g/mol) for analytical method development and quality control.

The molecular framework of 2-(Methacryloyloxy)ethyl 6-amino-4-(3-chloro-4-nitrophenyl)-5-cyano-2-methyl-4H-pyran-3-carboxylate (C20H18ClN3O7) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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), 2-(Methacryloyloxy)ethyl 6-amino-4-(3-chloro-4-nitrophenyl)-5-cyano-2-methyl-4H-pyran-3-carboxylate 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.
