Chemical Structure
Description
1-chloro-3-cyclopropylbutan-2-one (CAS 1555324-77-0), molecular formula C7H11ClO and molecular weight 146.61 g/mol, is a CATO reference standard with documented purity and traceability.
1-chloro-3-cyclopropylbutan-2-one (C7H11ClO) 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.
As a certified reference material (CRM), 1-chloro-3-cyclopropylbutan-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.
