(3R,4S,5R)-3-(acetyloxy)-4-(benzyloxy)-5-[(benzyloxy)methyl]-5-(fluoromethyl)oxolan-2-yl acetate CAS 196604-56-5 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (3R,4S,5R)-3-(acetyloxy)-4-(benzyloxy)-5-[(benzyloxy)methyl]-5-(fluoromethyl)oxolan-2-yl acetate.

(3R,4S,5R)-3-(acetyloxy)-4-(benzyloxy)-5-[(benzyloxy)methyl]-5-(fluoromethyl)oxolan-2-yl acetate (CAS 196604-56-5) is a high-purity analytical reference standard with the molecular formula C24H39FO7 and a molecular weight of 458.56 g/mol.

The molecular framework of (3R,4S,5R)-3-(acetyloxy)-4-(benzyloxy)-5-[(benzyloxy)methyl]-5-(fluoromethyl)oxolan-2-yl acetate (C24H39FO7) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
