Chemical Structure
Description
As a certified reference material (CRM), Ethyl 2-amino-2-cyanoacetate hemioxalate 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.
Ethyl 2-amino-2-cyanoacetate hemioxalate (CAS 75470-88-1) is a high-purity analytical reference standard with the molecular formula C5H8N2O2C2H2O4 and a molecular weight of 218.16 g/mol.
The molecular framework of Ethyl 2-amino-2-cyanoacetate hemioxalate (C5H8N2O2C2H2O4) is characterized by a carbohydrate-derived structure, an amide group. 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).
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.
