66232-90-4 Usage
Uses
Used in Plastics and Textile Industry:
Phosphine oxide, dipentylphenylis used as a flame retardant additive for enhancing the fire safety of plastics and textiles. It helps to reduce the flammability of these materials by releasing phosphorus-containing gases when exposed to heat, thereby interfering with the combustion process.
Used in Polyurethane Foam Production:
In the production of polyurethane foam, phosphine oxide, dipentylphenylis used as a processing aid. Its presence during the manufacturing process aids in the formation of the foam, improving the overall quality and performance of the final product.
Precautions:
Due to potential concerns for long-term health effects with prolonged exposure, it is important to take precautions to minimize exposure to phosphine oxide, dipentylphenylin industrial and commercial settings. This may include proper handling, storage, and usage guidelines to ensure the safety of workers and the environment.
Check Digit Verification of cas no
The CAS Registry Mumber 66232-90-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,2,3 and 2 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 66232-90:
(7*6)+(6*6)+(5*2)+(4*3)+(3*2)+(2*9)+(1*0)=124
124 % 10 = 4
So 66232-90-4 is a valid CAS Registry Number.

Copper-catalyzed P-arylation via direct coupling of diaryliodonium salts with phosphorus nucleophiles at room temperature

A new method for copper-catalyzed P-C bond formation through reaction of phosphorus nucleophiles with diaryliodonium salts at room temperature is described. Most target products are obtained with this method in high yields within a short reaction time of 10 min. It can be easily adapted to large-scale preparations. When unsymmetrical iodonium salts are employed, nucleophilic substitution occurs preferentially on the sterically hindered aromatic ring or the more electron-deficient ring.
