Chemical Structure
Description
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.
1,5-Dimethyl (2E,4Z)-4-[(benzylamino)methylidene]pent-2-enedioate (CAS 78408-80-7) is a high-purity analytical reference standard with the molecular formula C15H17NO4 and a molecular weight of 275.30 g/mol.
The molecular framework of 1,5-Dimethyl (2E,4Z)-4-[(benzylamino)methylidene]pent-2-enedioate (C15H17NO4) 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.
As a certified reference material (CRM), 1,5-Dimethyl (2E,4Z)-4-[(benzylamino)methylidene]pent-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.
