Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(E)-O-Ethyl O-(2-(isopropylthio)-1-phenylvinyl) S-propyl phosphorothioate (CAS 64878-66-6) is a high-purity analytical reference standard with the molecular formula C16H25O3PS2 and a molecular weight of 360.47 g/mol.
Structurally, (E)-O-Ethyl O-(2-(isopropylthio)-1-phenylvinyl) S-propyl phosphorothioate (C16H25O3PS2) contains a sulfone group, a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.5, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 360.47 g/mol, it falls into the moderately-high-molecular-weight range. 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).
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.
