Description
Compared with other compounds in its class, the molecular weight of 365.36 g/mol gives 5293-84-5 (Chloromethyl)triphenylphosphonium chloride Phosphonium, chloromethyltriphenyl-, chloride Chloromethyltriphenylphosphonium chloride EINECS 226-139-9 NSC 93980 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5293-84-5 (Chloromethyl)triphenylphosphonium chloride Phosphonium, chloromethyltriphenyl-, chloride Chloromethyltriphenylphosphonium chloride EINECS 226-139-9 NSC 93980 (CAS 5293-84-5) is a high-purity analytical reference standard with the molecular formula C19H35ClPCl and a molecular weight of 365.36 g/mol.
Based on its molecular formula C19H35ClPCl, 5293-84-5 (Chloromethyl)triphenylphosphonium chloride Phosphonium, chloromethyltriphenyl-, chloride Chloromethyltriphenylphosphonium chloride EINECS 226-139-9 NSC 93980 contains organophosphorus functionality, chlorine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 365.36 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.
