Description

Structurally, (2R)-1-tert-butoxycarbonyl-2-(4-fluorobenzyl)proline (2R)-1-tert-butoxycarbonyl-2-[(4-fluorophenyl)methyl]pyrrolidine-2-carboxylic acid (2R)-2-[(4-fluorophenyl)methyl]-1-[(2-methylpropan-2-yl)oxy-oxomethyl]-2-pyrrolidinecarboxylic acid (2R)-2-[(4-fluorophenyl)methyl]-1-[(2-methylpropan-2-yl)oxycarbonyl]pyrrolidine-2-carboxylic acid 706806-64-6 Boc-(R)-alpha-(4-fluorobenzyl)-proline (C17H28FNO4) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 329.41 g/mol, it falls into the moderately-high-molecular-weight range. 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).

(2R)-1-tert-butoxycarbonyl-2-(4-fluorobenzyl)proline (2R)-1-tert-butoxycarbonyl-2-[(4-fluorophenyl)methyl]pyrrolidine-2-carboxylic acid (2R)-2-[(4-fluorophenyl)methyl]-1-[(2-methylpropan-2-yl)oxy-oxomethyl]-2-pyrrolidinecarboxylic acid (2R)-2-[(4-fluorophenyl)methyl]-1-[(2-methylpropan-2-yl)oxycarbonyl]pyrrolidine-2-carboxylic acid 706806-64-6 Boc-(R)-alpha-(4-fluorobenzyl)-proline (CAS 706806-64-6) is a high-purity analytical reference standard with the molecular formula C17H28FNO4 and a molecular weight of 329.41 g/mol.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
