Chemical Structure

2-((4-Methoxyphenylamino)Methylene)Malonic Acid Diethyl Ester CAS 83507-70-4 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 2-((4-Methoxyphenylamino)Methylene)Malonic Acid Diethyl Ester.

2-((4-Methoxyphenylamino)Methylene)Malonic Acid Diethyl Ester (CAS 83507-70-4) is a high-purity analytical reference standard with the molecular formula C15H19NO5 and a molecular weight of 293.32 g/mol.

2-((4-Methoxyphenylamino)Methylene)Malonic Acid Diethyl Ester (C15H19NO5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).

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-((4-Methoxyphenylamino)Methylene)Malonic Acid Diethyl Ester 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.
