Chemical Structure
Description
CATO manufactures 5,7-Diiodobenzo[d]oxazol-2(3H)-one 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.
5,7-Diiodobenzo[d]oxazol-2(3H)-one (CAS 439107-30-9), molecular formula C7H3I2NO2 and molecular weight 386.91 g/mol, is a CATO reference standard with documented purity and traceability.
5,7-Diiodobenzo[d]oxazol-2(3H)-one (C7H3I2NO2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
