Chemical Structure

3,5-Dichloropentan-2-one CAS 58371-98-5 chemical structure

Description

Owing to a hydroxyl group, an ether linkage, chlorine substitution, 3,5-Dichloropentan-2-one is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 155.02 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

3,5-Dichloropentan-2-one (CAS 58371-98-5), molecular formula C5H8Cl2O and molecular weight 155.02 g/mol, is a CATO reference standard with documented purity and traceability.

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.
