Chemical Structure

1-Chloro-3-methylbutan-2-one CAS 17687-63-7 chemical structure

Description

As a certified reference material (CRM), 1-Chloro-3-methylbutan-2-one 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.

1-Chloro-3-methylbutan-2-one (CAS 17687-63-7), molecular formula C5H9ClO and molecular weight 120.58 g/mol, is a CATO reference standard with documented purity and traceability.

1-Chloro-3-methylbutan-2-one (C5H9ClO) 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.

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.
