Chemical Structure
Description
The occurrence of 4-(Di-tert-butylfluorosilyl)benzaldehyde is closely related to a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 4-(Di-tert-butylfluorosilyl)benzaldehyde (CAS 915023-44-8), a certified reference material (molecular formula C15H23FOSi, MW 266.43 g/mol) for analytical method development and quality control.
Owing to a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 4-(Di-tert-butylfluorosilyl)benzaldehyde is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 266.43 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
