(1-fluorocyclopentyl)methanesulfonyl chloride CAS 1803570-66-2

Description

Compared with other compounds in its class, the molecular weight of 200.66 g/mol gives (1-fluorocyclopentyl)methanesulfonyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(1-fluorocyclopentyl)methanesulfonyl chloride (CAS 1803570-66-2), molecular formula C6H10ClFO2S and molecular weight 200.66 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, (1-fluorocyclopentyl)methanesulfonyl chloride is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 200.66 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.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), (1-fluorocyclopentyl)methanesulfonyl chloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
