Description

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.

2,3,5-Tri-O-benzyl-1-O-(4-nitrobenzoyl)-D-arabinofuranose 2,3,5-tri-O-benzyl-1,0-(4-nitrobenzoyl)-D-arabinofuranose 5-Fluoro-2-iodobenzoic acid 52548-63-7 (CAS 52548-63-7), molecular formula C7H10FIO2 and molecular weight 272.06 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2,3,5-Tri-O-benzyl-1-O-(4-nitrobenzoyl)-D-arabinofuranose 2,3,5-tri-O-benzyl-1,0-(4-nitrobenzoyl)-D-arabinofuranose 5-Fluoro-2-iodobenzoic acid 52548-63-7 (C7H10FIO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 272.06 g/mol, it falls into the medium-molecular-weight range. 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.
