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.
Ethyl 3,6-dipentyl-3,6-dihydro-2H-thiopyran-2-carboxylate (CAS 176495-35-5), molecular formula C18H32O2S and molecular weight 312.51 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Ethyl 3,6-dipentyl-3,6-dihydro-2H-thiopyran-2-carboxylate (C18H32O2S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
