Description

CATO supplies 1,5-Diethyl (2E,4E)-4-{amino[4-(2,6-dimethylphenyl)piperazin-1-yl]methylidene}-2-cyanopent-2-enedioate (CAS 338406-32-9), a certified reference material (molecular formula C23H30N4O4, MW 426.51 g/mol) for analytical method development and quality control.

The molecular framework of 1,5-Diethyl (2E,4E)-4-{amino[4-(2,6-dimethylphenyl)piperazin-1-yl]methylidene}-2-cyanopent-2-enedioate (C23H30N4O4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. 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.

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), 1,5-Diethyl (2E,4E)-4-{amino[4-(2,6-dimethylphenyl)piperazin-1-yl]methylidene}-2-cyanopent-2-enedioate 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.
