Chemical Structure

2,6-Di-tert-butyl-4-chlorophenol CAS 4096-72-4 chemical structure

Description

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.

2,6-Di-tert-butyl-4-chlorophenol (CAS 4096-72-4) is a high-purity analytical reference standard with the molecular formula C14H21ClO and a molecular weight of 240.77 g/mol.

The molecular framework of 2,6-Di-tert-butyl-4-chlorophenol (C14H21ClO) is characterized by a hydroxyl group, an ether linkage, chlorine substitution, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
