Description
As a certified reference material (CRM), (Z)-4-((Dibromo(((E)-4-oxopent-2-en-2-yl)oxy)stannyl)oxy)pent-3-en-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.
(Z)-4-((Dibromo(((E)-4-oxopent-2-en-2-yl)oxy)stannyl)oxy)pent-3-en-2-one (CAS 16894-10-3), molecular formula C10H14Br2O4Sn and molecular weight 476.73 g/mol, is a CATO reference standard with documented purity and traceability.
(Z)-4-((Dibromo(((E)-4-oxopent-2-en-2-yl)oxy)stannyl)oxy)pent-3-en-2-one (C10H14Br2O4Sn) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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.
