4-Ethylsulfonyl-2-nitroanisole (CAS 51572-44-2) is a high-purity analytical reference standard with the molecular formula C9H11NO5S and a molecular weight of 245.25 g/mol.
4-Ethylsulfonyl-2-nitroanisole (C9H11NO5S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.
