Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 394.51 g/mol gives Disperse Red 1 Methacrylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Disperse Red 1 Methacrylate (CAS 103553-48-6), a certified reference material (molecular formula C20H34N4O4, MW 394.51 g/mol) for analytical method development and quality control.
Disperse Red 1 Methacrylate (C20H34N4O4) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
