Octadecanamide, N,N'-[1,2-ethanediylbis(imino-2,1-ethanediyl)]bis-, polymer with 2-(chloromethyl)oxirane CAS 72121-89-2 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 Octadecanamide, N,N'-[1,2-ethanediylbis(imino-2,1-ethanediyl)]bis-, polymer with 2-(chloromethyl)oxirane.

Octadecanamide, N,N'-[1,2-ethanediylbis(imino-2,1-ethanediyl)]bis-, polymer with 2-(chloromethyl)oxirane (CAS 72121-89-2), molecular formula C42H86N4O2C3H5ClO and molecular weight 771.70 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Octadecanamide, N,N'-[1,2-ethanediylbis(imino-2,1-ethanediyl)]bis-, polymer with 2-(chloromethyl)oxirane (C42H86N4O2C3H5ClO) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
