Chemical Structure
Description
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 3-Amino-3-(4,5-dimethoxy-2-nitrophenyl)propionic Acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 270.24 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).
3-Amino-3-(4,5-dimethoxy-2-nitrophenyl)propionic Acid (CAS 682804-28-0), molecular formula C11H14N2O6 and molecular weight 270.24 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.
