Chemical Structure

4-Trimethylsilyloxybenzaldehyde CAS 17869-75-9 chemical structure

Description

The occurrence of 4-Trimethylsilyloxybenzaldehyde is closely related to a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 4-Trimethylsilyloxybenzaldehyde (CAS 17869-75-9), a certified reference material (molecular formula C7H14OSi, MW 142.27 g/mol) for analytical method development and quality control.

The molecular framework of 4-Trimethylsilyloxybenzaldehyde (C7H14OSi) is characterized by a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

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.
