The occurrence of 4-((4-Methylpentyl)oxy)butane-1-sulfonyl chloride is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-((4-Methylpentyl)oxy)butane-1-sulfonyl chloride (CAS 1339766-33-4) is a high-purity analytical reference standard with the molecular formula C10H21ClO3S and a molecular weight of 256.79 g/mol.
Based on its molecular formula C10H21ClO3S, 4-((4-Methylpentyl)oxy)butane-1-sulfonyl chloride contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 256.79 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
