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.
4-((Trimethylsilyl)oxy)pent-3-en-2-one (CAS 13257-81-3) is a high-purity analytical reference standard with the molecular formula C8H16O2Si and a molecular weight of 172.30 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 4-((Trimethylsilyl)oxy)pent-3-en-2-one is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 172.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
