Chemical Structure
Description
Owing to deuterium isotope labeling, a nitrile group, Dalfampridine D4 is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 98.14 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).
Dalfampridine D4 (CAS 26257-21-6), molecular formula C5H2D4N2 and molecular weight 98.14 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
