Chemical Structure
Description
The occurrence of 【禁售不询】S-[2-(Diethylamino)ethyl]O，O-diethylphosphorothioate is closely related to an amide group, a sulfone group, a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
【禁售不询】S-[2-(Diethylamino)ethyl]O，O-diethylphosphorothioate (CAS 78-53-5) is a high-purity analytical reference standard with the molecular formula C10H24NO3PS and a molecular weight of 269.34 g/mol.
Structurally, 【禁售不询】S-[2-(Diethylamino)ethyl]O，O-diethylphosphorothioate (C10H24NO3PS) contains an amide group, a sulfone group, a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of -0.5, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 269.34 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
