Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 283.24 g/mol gives DNP-DL-norvaline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
DNP-DL-norvaline (CAS 31356-37-3) is a high-purity analytical reference standard with the molecular formula C11H13N3O6 and a molecular weight of 283.24 g/mol.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, DNP-DL-norvaline is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 283.24 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.
CATO manufactures DNP-DL-norvaline 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.
