Chemical Structure

1-(Trimethylsilyl)-3,5-dimethyl-4-methoxybenzene CAS 845823-17-8 chemical structure

Description

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.

1-(Trimethylsilyl)-3,5-dimethyl-4-methoxybenzene (CAS 845823-17-8), molecular formula C12H20OSi and molecular weight 208.37 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a hydroxyl group, an ether linkage, 1-(Trimethylsilyl)-3,5-dimethyl-4-methoxybenzene is typically white to off-white low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 208.37 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
