Chemical Structure

S-sec-Butyl Phosphorothioic Dichloride CAS 63525-20-2 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 207.06 g/mol gives S-sec-Butyl Phosphorothioic Dichloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

S-sec-Butyl Phosphorothioic Dichloride (CAS 63525-20-2) is a high-purity analytical reference standard with the molecular formula C4H9Cl2OPS and a molecular weight of 207.06 g/mol.

Based on its molecular formula C4H9Cl2OPS, S-sec-Butyl Phosphorothioic Dichloride contains sulfur-containing functionality, organophosphorus functionality, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 207.06 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.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
