Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4-Methyl-2-nitrobenzene-1-sulfonyl Chloride (CAS 54090-41-4), molecular formula C15H11I3NO4Na and molecular weight 672.95 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a salt form, a flavonoid core, an amide group, a hydroxyl group, an ether linkage, iodine substitution, 4-Methyl-2-nitrobenzene-1-sulfonyl Chloride is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 672.95 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
As a certified reference material (CRM), 4-Methyl-2-nitrobenzene-1-sulfonyl Chloride 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.
