Chemical Structure
Description
2-Bromo-4-(1,1,3,3-tetramethylbutyl)phenol (CAS 57835-35-5) is a high-purity analytical reference standard with the molecular formula C14H21BrO and a molecular weight of 285.22 g/mol.
The molecular framework of 2-Bromo-4-(1,1,3,3-tetramethylbutyl)phenol (C14H21BrO) is characterized by a hydroxyl group, an ether linkage, bromine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
