Chemical Structure

Tert-Butyl-4-Hydroxyanisole (Mixture Of 2- And 3-Isomer) CAS 25013-16-5 chemical structure

Description

The molecular framework of Tert-Butyl-4-Hydroxyanisole (Mixture Of 2- And 3-Isomer) (C11H16O2) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Tert-Butyl-4-Hydroxyanisole (Mixture Of 2- And 3-Isomer) (CAS 25013-16-5), molecular formula C11H16O2 and molecular weight 180.25 g/mol, is a CATO reference standard with documented purity and traceability.

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.
