Chemical Structure

1-Iodo-4-methoxybutane CAS 20549-69-3 chemical structure

Description

1-Iodo-4-methoxybutane (CAS 20549-69-3) is a high-purity analytical reference standard with the molecular formula C5H11IO and a molecular weight of 214.04 g/mol.

Owing to a hydroxyl group, an ether linkage, iodine substitution, 1-Iodo-4-methoxybutane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 214.04 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.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
