629-93-6 1-Iodooctadecane Octadecane, 1-iodo- EINECS 211-117-3 NSC 5544 Octadecyl iodide Stearyl iodide (CAS 629-93-6) is a high-purity analytical reference standard with the molecular formula C18H37I and a molecular weight of 380.39 g/mol.
Structurally, 629-93-6 1-Iodooctadecane Octadecane, 1-iodo- EINECS 211-117-3 NSC 5544 Octadecyl iodide Stearyl iodide (C18H37I) contains iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 0.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 380.39 g/mol, it falls into the moderately-high-molecular-weight range. 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.
