Chemical Structure

(1S,2S)-2-Chloro-2-Fluoro-1-Methylcyclopropanecarbonyl Chloride CAS 130340-07-7 chemical structure

Description

(1S,2S)-2-Chloro-2-Fluoro-1-Methylcyclopropanecarbonyl Chloride (C5H5Cl2FO) contains a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

CATO supplies (1S,2S)-2-Chloro-2-Fluoro-1-Methylcyclopropanecarbonyl Chloride (CAS 130340-07-7), a certified reference material (molecular formula C5H5Cl2FO, MW 171.00 g/mol) for analytical method development and quality control.

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.
