Chemical Structure

1-Chlorocyclopropanecarbonyl chloride CAS 73492-25-8 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 138.98 g/mol gives 1-Chlorocyclopropanecarbonyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 1-Chlorocyclopropanecarbonyl chloride (CAS 73492-25-8), a certified reference material (molecular formula C4H4Cl2O, MW 138.98 g/mol) for analytical method development and quality control.

1-Chlorocyclopropanecarbonyl chloride (C4H4Cl2O) contains a hydroxyl group, an ether linkage, 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.

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.
