Chemical Structure

3,5-Dimethylheptane CAS 926-82-9 chemical structure

Description

The molecular framework of 3,5-Dimethylheptane (C9H20) is characterized by an organic framework. In reversed-phase chromatography, its retention is governed primarily by its non-polar molecular character, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

3,5-Dimethylheptane (CAS 926-82-9) is a high-purity analytical reference standard with the molecular formula C9H20 and a molecular weight of 128.26 g/mol.

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.
