Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,2-Ethanediamine, N1-(2-aminoethyl)-, polymer with 1,6-diisocyanatohexane.
1,2-Ethanediamine, N1-(2-aminoethyl)-, polymer with 1,6-diisocyanatohexane (CAS 65328-78-1), molecular formula C8H12N2O2C4H13N3 and molecular weight 271.37 g/mol, is a CATO reference standard with documented purity and traceability.
1,2-Ethanediamine, N1-(2-aminoethyl)-, polymer with 1,6-diisocyanatohexane (C8H12N2O2C4H13N3) contains 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.
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.
