Description
(2S,4S)-4-[[(3-Methoxyphenyl)methyl]amino]-1,2-pyrrolidinedicarboxylic Acid 1-(1,1-Dimethylethyl) 2-Methyl Ester (CAS 334999-43-8) is a high-purity analytical reference standard with the molecular formula C19H28N2O5 and a molecular weight of 364.44 g/mol.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, (2S,4S)-4-[[(3-Methoxyphenyl)methyl]amino]-1,2-pyrrolidinedicarboxylic Acid 1-(1,1-Dimethylethyl) 2-Methyl Ester is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 364.44 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.
