Chemical Structure
Description
The occurrence of 3-[(tert-butyldimethylsilyl)oxy]-2,4,6-trichlorophenol is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-[(tert-butyldimethylsilyl)oxy]-2,4,6-trichlorophenol (CAS 1781241-34-6), molecular formula C12H17Cl3O2Si and molecular weight 327.71 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 3-[(tert-butyldimethylsilyl)oxy]-2,4,6-trichlorophenol is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 327.71 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
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.
CATO manufactures 3-[(tert-butyldimethylsilyl)oxy]-2,4,6-trichlorophenol 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.
