5-Fluoropentanoyl Chloride CAS 353-04-8 chemical structure

Description

5-Fluoropentanoyl Chloride (CAS 353-04-8), molecular formula C5H8ClFO and molecular weight 138.57 g/mol, is a CATO reference standard with documented purity and traceability.

5-Fluoropentanoyl Chloride (C5H8ClFO) 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.

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), 5-Fluoropentanoyl 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.
