Chemical Structure

THIOPHOSPHORYL CHLORIDE CAS 3982-91-0 chemical structure

Description

Based on its molecular formula Cl3PS, THIOPHOSPHORYL CHLORIDE contains sulfur-containing functionality, organophosphorus functionality, chlorine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 169.40 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

THIOPHOSPHORYL CHLORIDE (CAS 3982-91-0), molecular formula Cl3PS and molecular weight 169.40 g/mol, is a CATO reference standard with documented purity and traceability.
