Chemical Structure
Description
(5-ethoxy-5-oxopentyl)zinc(II) bromide 265330-98-1 5-Ethoxy-5-oxopentylzinc bromide (CAS 265330-98-1) is a high-purity analytical reference standard with the molecular formula C7H13BrO2Zn and a molecular weight of 274.49 g/mol.
(5-ethoxy-5-oxopentyl)zinc(II) bromide 265330-98-1 5-Ethoxy-5-oxopentylzinc bromide (C7H13BrO2Zn) contains a salt form, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, 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.
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.
As a certified reference material (CRM), (5-ethoxy-5-oxopentyl)zinc(II) bromide 265330-98-1 5-Ethoxy-5-oxopentylzinc bromide 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.
