Phenylmethanamine (2S,4S)-1-(tert-butoxycarbonyl)-4-hydroxypiperidine-2-carboxylate (CAS 441044-14-0) is a high-purity analytical reference standard with the molecular formula C11H19NO5C7H9N and a molecular weight of 352.43 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, Phenylmethanamine (2S,4S)-1-(tert-butoxycarbonyl)-4-hydroxypiperidine-2-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 352.43 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.
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.
