Description
1171920-09-4 3-((Trimethylsilyl)ethynyl)pyridin-4-ol 9860AC C10H13NOSi (CAS 1171920-09-4) is a high-purity analytical reference standard with the molecular formula C10H13NOSi and a molecular weight of 191.30 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 1171920-09-4 3-((Trimethylsilyl)ethynyl)pyridin-4-ol 9860AC C10H13NOSi is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 191.30 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.
