CATO supplies L-Tyrosine, O-(1,1-dimethylethyl)-N-[(9H-fluoren-9-ylmethoxy)carbonyl]-, (1R)-2-carboxy-2-[[(1,1-dimethylethoxy)carbonyl]amino]-1-methylethyl ester (CAS 944283-41-4), a certified reference material (molecular formula C37H44N2O9, MW 660.75 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, L-Tyrosine, O-(1,1-dimethylethyl)-N-[(9H-fluoren-9-ylmethoxy)carbonyl]-, (1R)-2-carboxy-2-[[(1,1-dimethylethoxy)carbonyl]amino]-1-methylethyl ester is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 660.75 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.
