Chemical Structure
Description
As a certified reference material (CRM), 2-Methyl-4-nitroaniline-d3 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.
CATO supplies 2-Methyl-4-nitroaniline-d3 (CAS 1246815-44-0), a certified reference material (molecular formula C7H5D3N2O2, MW 155.17 g/mol) for analytical method development and quality control.
2-Methyl-4-nitroaniline-d3 (C7H5D3N2O2) contains deuterium isotope labeling, an amino-acid-derived structure, 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. 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.
