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-Nitrophenyl a-D-maltoheptaoside (CAS 74173-31-2) is a high-purity analytical reference standard with the molecular formula C48H75NO38 and a molecular weight of 1274.09 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 4-Nitrophenyl a-D-maltoheptaoside is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 1274.09 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).
CATO manufactures 4-Nitrophenyl a-D-maltoheptaoside 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.
