Chemical Structure
Description
CATO supplies 1-Cyclopentylbutan-1-one (CAS 6635-68-3), a certified reference material (molecular formula C9H16O, MW 140.22 g/mol) for analytical method development and quality control.
Owing to a hydroxyl group, an ether linkage, 1-Cyclopentylbutan-1-one is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 140.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
