Chemical Structure
Description
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 3-[(tert-Butyldimethylsilyl)oxy]-4-chlorophenol is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 258.82 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).
3-[(tert-Butyldimethylsilyl)oxy]-4-chlorophenol (CAS 1197814-23-5), molecular formula C12H19ClO2Si and molecular weight 258.82 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
