5927-50-4 Usage
General Description
Tetramethyl ethylenediphosphonate is a phosphorus-containing compound with the molecular formula C6H18O6P4. It is commonly used as a flame retardant and a chelating agent in various industrial applications. This chemical is highly effective in preventing the spread of fire and is often used in the production of textiles, plastics, and rubber products. Additionally, tetramethyl ethylenediphosphonate is used as a sequestering agent in water treatment and as a scale inhibitor in various industrial processes. Its ability to form stable complexes with metal ions makes it an important component in many chemical processes, including the production of pharmaceuticals and detergents. Despite its usefulness, tetramethyl ethylenediphosphonate should be handled with care and stored properly, as it can be toxic if ingested or inhaled and can cause irritation to the skin and eyes.
Check Digit Verification of cas no
The CAS Registry Mumber 5927-50-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,9,2 and 7 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 5927-50:
(6*5)+(5*9)+(4*2)+(3*7)+(2*5)+(1*0)=114
114 % 10 = 4
So 5927-50-4 is a valid CAS Registry Number.

Abstract A convenient and versatile method was developed for the preparation of 1,2-bisphosphorylethanes. Thus, in the presence of a catalytic amount of trimethylphosphine, a variety of >P(O)H compounds efficiently add to vinylphosphoryl compounds to produce the corresponding 1,2-bisphosphorylethanes in high yields. In most cases, the trimethylphosphine catalyst was simply removed under vacuum leaving spectroscopically pure adducts. The present method provided a halogen and metal-free clean process for the preparation of 1,2-bisphosphorylethanes.
