Description
CATO manufactures 4-[(4-Fluorobenzyl)oxy]benzyl 3-nitrobenzenecarboxylate 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.
4-[(4-Fluorobenzyl)oxy]benzyl 3-nitrobenzenecarboxylate (CAS 331461-75-7) is a high-purity analytical reference standard with the molecular formula C21H16FNO5 and a molecular weight of 381.35 g/mol.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 4-[(4-Fluorobenzyl)oxy]benzyl 3-nitrobenzenecarboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 381.35 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
