Chemical Structure

4-Chlorobutyryl Chloride CAS 4635-59-0 chemical structure

Description

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.

CATO supplies 4-Chlorobutyryl Chloride (CAS 4635-59-0), a certified reference material (molecular formula C4H6Cl2O, MW 141.00 g/mol) for analytical method development and quality control.

4-Chlorobutyryl Chloride (C4H6Cl2O) 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.

As a certified reference material (CRM), 4-Chlorobutyryl 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.
