Chemical Structure

1-Methyl-3-propylbenzene CAS 1074-43-7 chemical structure

Description

The molecular framework of 1-Methyl-3-propylbenzene (C10H14) is characterized by an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

1-Methyl-3-propylbenzene (CAS 1074-43-7) is a high-purity analytical reference standard with the molecular formula C10H14 and a molecular weight of 134.22 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.
