Chemical Structure

Lawesson's reagent CAS 19172-47-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 416.56 g/mol gives Lawesson's reagent distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Lawesson's reagent (CAS 19172-47-5) is a high-purity analytical reference standard with the molecular formula C14H26O2P2S4 and a molecular weight of 416.56 g/mol.

Structurally, Lawesson's reagent (C14H26O2P2S4) contains a sulfone group, organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 416.56 g/mol, it falls into the moderately-high-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.
