Chemical Structure

1-(But-3-en-1-yl)-4-methoxybenzene CAS 20574-98-5 chemical structure

Description

1-(But-3-en-1-yl)-4-methoxybenzene (CAS 20574-98-5) is a high-purity analytical reference standard with the molecular formula C11H14O and a molecular weight of 162.23 g/mol.

The molecular framework of 1-(But-3-en-1-yl)-4-methoxybenzene (C11H14O) is characterized by a hydroxyl group, an ether linkage, 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.

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.
