Chemical Structure
Description
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.
CATO supplies 5,6-dihydro-2H-cyclopenta[c]pyrrol-4-one (CAS 95065-06-8), a certified reference material (molecular formula C7H11NO, MW 125.17 g/mol) for analytical method development and quality control.
Owing to an amide group, a hydroxyl group, an ether linkage, 5,6-dihydro-2H-cyclopenta[c]pyrrol-4-one is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 125.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
