287484-30-4 L-(N~2~-~15~N)Asparagine--water (1/1) DTXSID20583961 CAS 287484-30-4

Description

The molecular framework of 287484-30-4 L-(N~2~-~15~N)Asparagine--water (1/1) DTXSID20583961 (C4H8N[15N]O3 H2O) is characterized by a carbohydrate-derived structure, an amide group. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

CATO supplies 287484-30-4 L-(N~2~-~15~N)Asparagine--water (1/1) DTXSID20583961 (CAS 287484-30-4), a certified reference material (molecular formula C4H8N[15N]O3 H2O, MW 150.13 g/mol) for analytical method development and quality control.

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.
