Chemical Structure

2-Chloroethyl 2,2,2-trifluoroacetate CAS 40949-99-3 chemical structure

Description

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 2-Chloroethyl 2,2,2-trifluoroacetate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 176.52 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.

2-Chloroethyl 2,2,2-trifluoroacetate (CAS 40949-99-3), molecular formula C4H4ClF3O2 and molecular weight 176.52 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.
