Chemical Structure

rel-(1R,2S,4r)-1,2-difluoro-4-(iodomethyl)cyclopentane CAS 1036721-60-4 chemical structure

Description

Owing to fluorine/iodine substitution, rel-(1R,2S,4r)-1,2-difluoro-4-(iodomethyl)cyclopentane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 246.04 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.

rel-(1R,2S,4r)-1,2-difluoro-4-(iodomethyl)cyclopentane (CAS 1036721-60-4), molecular formula C6H9F2I and molecular weight 246.04 g/mol, is a CATO reference standard with documented purity and traceability.

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.
