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 Urea, polymer with N,N-bis(2-hydroxyethyl)octadecanamide.
Urea, polymer with N,N-bis(2-hydroxyethyl)octadecanamide (CAS 68368-46-7), molecular formula C22H45NO3CH4N2O and molecular weight 431.66 g/mol, is a CATO reference standard with documented purity and traceability.
Urea, polymer with N,N-bis(2-hydroxyethyl)octadecanamide (C22H45NO3CH4N2O) contains an amide 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.
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.
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.
