Chemical Structure
Description
22-Bromo-3-methoxy-2,5,8,11,14,17,20-heptaoxadocosane (CAS 2874308-68-4), molecular formula C16H33BrO8 and molecular weight 433.33 g/mol, is a CATO reference standard with documented purity and traceability.
22-Bromo-3-methoxy-2,5,8,11,14,17,20-heptaoxadocosane (C16H33BrO8) contains 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.
CATO manufactures 22-Bromo-3-methoxy-2,5,8,11,14,17,20-heptaoxadocosane under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
