Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 322.40 g/mol gives (3,3-Dimethyl-3,4-dihydroisoquinolin-1-yl)phenylalanine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(3,3-Dimethyl-3,4-dihydroisoquinolin-1-yl)phenylalanine (CAS 1397005-80-9), molecular formula C20H22N2O2 and molecular weight 322.40 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, (3,3-Dimethyl-3,4-dihydroisoquinolin-1-yl)phenylalanine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 322.40 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
