Chemical Structure
Description
The molecular framework of 7-Allyl-6-hydroxy-4,4,5,8-tetramethylchroman-2-one (C16H26O3) is characterized by a carboxylic acid group, 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
7-Allyl-6-hydroxy-4,4,5,8-tetramethylchroman-2-one (CAS 219938-56-4) is a high-purity analytical reference standard with the molecular formula C16H26O3 and a molecular weight of 266.38 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.
