Description
Compared with other compounds in its class, the molecular weight of 233.13 g/mol gives 1-Chloro-4-((5-chloropentyl)oxy)benzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-Chloro-4-((5-chloropentyl)oxy)benzene (CAS 81956-16-3), molecular formula C11H14Cl2O and molecular weight 233.13 g/mol, is a CATO reference standard with documented purity and traceability.
1-Chloro-4-((5-chloropentyl)oxy)benzene (C11H14Cl2O) 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. 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-4-((5-chloropentyl)oxy)benzene 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.
