Chemical Structure

2,2,3,4-Tetramethylbutyrophenone CAS 898765-64-5 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.

2,2,3,4-Tetramethylbutyrophenone (CAS 898765-64-5) is a high-purity analytical reference standard with the molecular formula C14H20O and a molecular weight of 204.31 g/mol.

Based on its molecular formula C14H20O, 2,2,3,4-Tetramethylbutyrophenone contains a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 204.31 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
