Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 1-Nitro-2-tosylbenzene is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 277.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
1-Nitro-2-tosylbenzene (CAS 1220-92-4) is a high-purity analytical reference standard with the molecular formula C13H11NO4S and a molecular weight of 277.30 g/mol.
