Methylpentachlorofluorophosphorane, also known as methyl nonafluoropentane, is a colorless, volatile, and highly toxic organophosphorus compound with the chemical formula CCl5PF3. It is a derivative of phosphorus pentachloride, where three of the chlorine atoms are replaced by fluorine atoms, and one hydrogen atom is replaced by a methyl group. METHYLPENTAFLUOROPHOSPHORANE is primarily used as a precursor in the synthesis of various organophosphorus compounds, such as pesticides and flame retardants. Due to its high reactivity and potential health risks, it is essential to handle methylpentachlorofluorophosphorane with extreme caution and proper safety measures.

420-64-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 420-64-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,2 and 0 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 420-64:
(5*4)+(4*2)+(3*0)+(2*6)+(1*4)=44
44 % 10 = 4
So 420-64-4 is a valid CAS Registry Number.

A Very Strong Methylation Agent: [Me2Cl][Al(OTeF5)4]

H?mmerling, Sebastian,Thiele, Günther,Steinhauer, Simon,Beckers, Helmut,Müller, Carsten,Riedel, Sebastian

supporting information, p. 9807 - 9810 (2019/06/24)

A new chloronium-containing salt, [Me2Cl][Al(OTeF5)4], was synthesized on multigram scale by means of a simple one-pot procedure. The isolated product can be handled at room temperature and used as a strong electrophilic methylation agent. This is demonstrated by the methylation of the very weak bases P(CF3)3, PF3, MeI, and MeBr.
