Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 205.17 g/mol gives Diethyl Nitromalonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Diethyl Nitromalonate (CAS 603-67-8), a certified reference material (molecular formula C7H11NO6, MW 205.17 g/mol) for analytical method development and quality control.
Diethyl Nitromalonate (C7H11NO6) contains a carbohydrate-derived structure, an amide group. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), Diethyl Nitromalonate 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.
