Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-(Benzyloxy)-N-ethyl-2-nitroaniline.
CATO supplies 5-(Benzyloxy)-N-ethyl-2-nitroaniline (CAS 1266247-03-3), a certified reference material (molecular formula C15H16N2O3, MW 272.30 g/mol) for analytical method development and quality control.
5-(Benzyloxy)-N-ethyl-2-nitroaniline (C15H16N2O3) contains a nitrogen-containing heterocyclic scaffold, 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
