Description
As a certified reference material (CRM), 1-(4-Chlorophenyl)cyclobutanecarbonyl 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.
1-(4-Chlorophenyl)cyclobutanecarbonyl chloride (CAS 89421-95-4) is a high-purity analytical reference standard with the molecular formula C11H10Cl2O and a molecular weight of 229.10 g/mol.
1-(4-Chlorophenyl)cyclobutanecarbonyl chloride (C11H10Cl2O) contains a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
