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.
(Tetrahydro-thiopyran-4-yl)-acetaldehyde (CAS 372159-78-9), molecular formula C7H12OS and molecular weight 144.23 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, (Tetrahydro-thiopyran-4-yl)-acetaldehyde is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 144.23 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.
