N,n-dimethylaminomethylenemalonicaciddimethylester (CAS 18856-69-4) is a high-purity analytical reference standard with the molecular formula C8H13NO4 and a molecular weight of 187.19 g/mol.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, N,n-dimethylaminomethylenemalonicaciddimethylester is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 187.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
