2-(Methacryloyloxy)ethyl 6-amino-5-cyano-4-(3,4-dichlorophenyl)-2-methyl-4H-pyran-3-carboxylate CAS 939888-90-1

Description

The molecular framework of 2-(Methacryloyloxy)ethyl 6-amino-5-cyano-4-(3,4-dichlorophenyl)-2-methyl-4H-pyran-3-carboxylate (C20H18Cl2N2O5) 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

2-(Methacryloyloxy)ethyl 6-amino-5-cyano-4-(3,4-dichlorophenyl)-2-methyl-4H-pyran-3-carboxylate (CAS 939888-90-1), molecular formula C20H18Cl2N2O5 and molecular weight 437.27 g/mol, is a CATO reference standard with documented purity and traceability.

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-5-cyano-4-(3,4-dichlorophenyl)-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.
