Description
CATO manufactures 3,5-Difluoro-4-nitrobenzyl Alcohol 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.
3,5-Difluoro-4-nitrobenzyl Alcohol (CAS 1123172-89-3), molecular formula C7H5F2NO3 and molecular weight 189.12 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 3,5-Difluoro-4-nitrobenzyl Alcohol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 189.12 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.
