Chemical Structure
Description
CATO supplies 9,10-Dibromoanthracene-2-sulfonic Acid, Sodium Salt (CAS 87796-18-7), a certified reference material (molecular formula C14H7Br2NaO3S, MW 438.07 g/mol) for analytical method development and quality control.
9,10-Dibromoanthracene-2-sulfonic Acid, Sodium Salt (C14H7Br2NaO3S) contains a salt form, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system. 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 9,10-Dibromoanthracene-2-sulfonic Acid, Sodium Salt 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.
