Chemical Structure

4-tert-Butyldimethylsiloxyacetophenone CAS 149683-53-4 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.

4-tert-Butyldimethylsiloxyacetophenone (CAS 149683-53-4) is a high-purity analytical reference standard with the molecular formula C14H22O2Si and a molecular weight of 250.41 g/mol.

Based on its molecular formula C14H22O2Si, 4-tert-Butyldimethylsiloxyacetophenone contains a carboxylic acid group, 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 250.41 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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 4-tert-Butyldimethylsiloxyacetophenone 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.
