Chemical Structure

2,6-Di-Tert-Butyl-1,4-Benzoquinone CAS 719-22-2 chemical structure

Description

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.

2,6-Di-Tert-Butyl-1,4-Benzoquinone (CAS 719-22-2) is a high-purity analytical reference standard with the molecular formula C14H20O2 and a molecular weight of 220.31 g/mol.

The molecular framework of 2,6-Di-Tert-Butyl-1,4-Benzoquinone (C14H20O2) 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).

CATO manufactures 2,6-Di-Tert-Butyl-1,4-Benzoquinone under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
