Description
1-Iodo-2,3-dimethyl-4-nitrobenzene (CAS 79424-74-1), molecular formula C8H8INO2 and molecular weight 277.06 g/mol, is a CATO reference standard with documented purity and traceability.
1-Iodo-2,3-dimethyl-4-nitrobenzene (C8H8INO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, iodine 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1-Iodo-2,3-dimethyl-4-nitrobenzene 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.
