Chemical Structure
Description
The occurrence of 3-(2-Amino-phenylamino)-2-cyano-acrylic acid ethyl ester is closely related to an amide group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 3-(2-Amino-phenylamino)-2-cyano-acrylic acid ethyl ester (CAS 21025-47-8), a certified reference material (molecular formula C10H19N2O5P, MW 278.24 g/mol) for analytical method development and quality control.
3-(2-Amino-phenylamino)-2-cyano-acrylic acid ethyl ester (C10H19N2O5P) contains an amide group, a phosphate ester group, a carboxylic acid 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.
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.
