Chemical Structure

(R)-4-(Iodomethyl)dihydrofuran-2(3H)-one CAS 88557-21-5 chemical structure

Description

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.

(R)-4-(Iodomethyl)dihydrofuran-2(3H)-one (CAS 88557-21-5), molecular formula C5H7IO2 and molecular weight 226.01 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, (R)-4-(Iodomethyl)dihydrofuran-2(3H)-one is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 226.01 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
