Chemical Structure

2-Methylheptadecane CAS 1560-89-0 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 254.49 g/mol gives 2-Methylheptadecane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Methylheptadecane (CAS 1560-89-0) is a high-purity analytical reference standard with the molecular formula C18H38 and a molecular weight of 254.49 g/mol.

Owing to an organic framework, 2-Methylheptadecane is typically white to off-white low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 254.49 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.

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.

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.
