Chemical Structure

N2-Butyl-N4-(3,5-dimethylphenyl)-L-asparagine CAS 1047677-75-7 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 N2-Butyl-N4-(3,5-dimethylphenyl)-L-asparagine.

N2-Butyl-N4-(3,5-dimethylphenyl)-L-asparagine (CAS 1047677-75-7), molecular formula C16H24N2O3 and molecular weight 292.37 g/mol, is a CATO reference standard with documented purity and traceability.

N2-Butyl-N4-(3,5-dimethylphenyl)-L-asparagine (C16H24N2O3) contains a nitrogen-containing heterocyclic scaffold, 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.

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.
