Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2,4-Diiodo-1,3,5-trimethylbenzene (CAS 53779-84-3), molecular formula C9H10I2 and molecular weight 371.98 g/mol, is a CATO reference standard with documented purity and traceability.
2,4-Diiodo-1,3,5-trimethylbenzene (C9H10I2) contains iodine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures 2,4-Diiodo-1,3,5-trimethylbenzene 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.
