3-(((tert-Butyldiphenylsilyl)oxy)methyl)-5-ethynyl-1-methyl-1H-pyrazole (CAS 2245716-56-5) is a high-purity analytical reference standard with the molecular formula C23H26N2OSi and a molecular weight of 374.55 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 3-(((tert-Butyldiphenylsilyl)oxy)methyl)-5-ethynyl-1-methyl-1H-pyrazole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 374.55 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.
