1499-29-2 Usage
General Description
Methylenebis(phosphonic dichloride) is a chemical compound with the molecular formula C2H6Cl2O4P2. It is a phosphorus-containing compound that is used as a key intermediate in the synthesis of a wide range of phosphonate-based chemicals, including water treatment chemicals, flame retardants, and pharmaceuticals. It is a clear, colorless liquid that is highly reactive and can pose health hazards if not handled properly. Methylenebis(phosphonic dichloride) is commonly used in industrial processes for its ability to effectively bind to metal ions and inhibit the formation of scale and corrosion in water systems. Due to its potential hazards, it should be handled with caution and in accordance with proper safety measures.
Check Digit Verification of cas no
The CAS Registry Mumber 1499-29-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,9 and 9 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1499-29:
(6*1)+(5*4)+(4*9)+(3*9)+(2*2)+(1*9)=102
102 % 10 = 2
So 1499-29-2 is a valid CAS Registry Number.

Preparation of organohalosilanes
-
, (2008/06/13)
In an industrial process for preparing organohalosilanes by reacting metallic silicon particles with an organohalide in the presence of a copper catalyst, a contact mass composed of the metallic silicon and the catalyst further contains an effective amount of a phosphine chalcogenide compound. The invention drastically increases the silane formation rate and the utilization of silicon without lowering the selectivity of useful silane.
