Dimethoxyphosphanyl dimethyl phosphate, also known as dimethoxyphosphoryl dimethyl phosphate or (dimethoxyphosphoryl)dimethyl phosphate, is a chemical compound with the molecular formula C4H11O6P2. It is an organophosphorus compound that consists of a central phosphorus atom bonded to two oxygen atoms, one dimethoxyphosphanyl group (P(OCH3)2), and one dimethyl phosphate group (P(O)(OCH3)2). dimethoxyphosphanyl dimethyl phosphate is a colorless liquid with a density of 1.31 g/cm3 and a boiling point of 85-87°C at 20 mmHg. It is soluble in organic solvents and has a low vapor pressure. Dimethoxyphosphanyl dimethyl phosphate is primarily used as a precursor in the synthesis of various organophosphorus compounds, including pesticides, flame retardants, and other specialty chemicals. Due to its reactivity and potential toxicity, it is important to handle this compound with care and follow proper safety protocols.

1067-83-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1067-83-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,6 and 7 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1067-83:
(6*1)+(5*0)+(4*6)+(3*7)+(2*8)+(1*3)=70
70 % 10 = 0
So 1067-83-0 is a valid CAS Registry Number.

Dynamic Equilibria between Pentavalent Protonated Oxyphosphoranes and Their Isomeric Tetravalent Enol Phosphonium Ions via Inter- and Intramolecular Proton Transfer

Castelijns, Marianne M. C. F.,Schipper, Pieter,Aken, Dirk van,Buck, Henk M.

, p. 47 - 53 (2007/10/02)

Low-temperature NMR (1H, 13C, 31P) measurements of the reaction of several pentavalent oxyphosphoranes with FSO3H in CH2Cl2 are described.Rapid equilibria between the neutral oxyphosphoranes and the enol phosphonium ions involving an intermolecular proton transfer can be obtained by implying certain structural constraints on the system, which means that less entropy has to be expended in order to obtain the rigid closed form of the protonated oxyphosphorane.Moreover, in one case evidence is presented for an intramolecular proton-exchange process which is also controlled by an intermediary pentavalent protonated oxyphosphorane.These reactions may be regarded as a model for intramolecular (biological) phosphorylation processes.
