Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-Butyl-2-(2,4-dichlorophenyl)oxirane (CAS 88374-07-6) is a high-purity analytical reference standard with the molecular formula C12H14Cl2O and a molecular weight of 245.14 g/mol.
Owing to a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 2-Butyl-2-(2,4-dichlorophenyl)oxirane is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 245.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
