Description
CATO supplies 1-Acetyl-4-amino-2,5-dihydro-1H-pyrrole-3-carbonitrile (CAS 2125-74-8), a certified reference material (molecular formula C7H9N3O, MW 151.17 g/mol) for analytical method development and quality control.
1-Acetyl-4-amino-2,5-dihydro-1H-pyrrole-3-carbonitrile (C7H9N3O) contains an amide group, a hydroxyl group, an ether linkage, an aromatic ring system. Its physicochemical properties are representative of its class; 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.
