Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N5-((R)-1-((Carboxymethyl)amino)-3-(((5S,6R,7E,9E,11Z,14Z)-5-hydroxy-1-methoxy-1-oxoicosa-7,9,11,14-tetraen-6-yl)thio)-1-oxopropan-2-yl)-L-glutamine.
N5-((R)-1-((Carboxymethyl)amino)-3-(((5S,6R,7E,9E,11Z,14Z)-5-hydroxy-1-methoxy-1-oxoicosa-7,9,11,14-tetraen-6-yl)thio)-1-oxopropan-2-yl)-L-glutamine (CAS 73958-10-8) is a high-purity analytical reference standard with the molecular formula C31H49N3O9S and a molecular weight of 639.80 g/mol.
N5-((R)-1-((Carboxymethyl)amino)-3-(((5S,6R,7E,9E,11Z,14Z)-5-hydroxy-1-methoxy-1-oxoicosa-7,9,11,14-tetraen-6-yl)thio)-1-oxopropan-2-yl)-L-glutamine (C31H49N3O9S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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).
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.
