Chemical Structure

1-Chlorooctadecane CAS 3386-33-2 chemical structure

Description

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.

1-Chlorooctadecane (CAS 3386-33-2) is a high-purity analytical reference standard with the molecular formula C18H37Cl and a molecular weight of 288.94 g/mol.

Owing to chlorine substitution, 1-Chlorooctadecane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 288.94 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.
