Chemical Structure

1-(But-3-yn-1-yl)pyrrolidin-2-one CAS 51622-65-2 chemical structure

Description

1-(But-3-yn-1-yl)pyrrolidin-2-one (C8H11NO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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.

CATO supplies 1-(But-3-yn-1-yl)pyrrolidin-2-one (CAS 51622-65-2), a certified reference material (molecular formula C8H11NO, MW 137.18 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.
