Benzyl methyl(phenyl)phosphinate is an organophosphorus compound with the chemical formula C15H15O2P. It is a colorless to pale yellow liquid and is soluble in organic solvents. benzyl methyl(phenyl)phosphinate is primarily used as a flame retardant and plasticizer in various materials, including plastics, rubber, and textiles. It functions by releasing phosphorus-based compounds when exposed to heat, which can interrupt the combustion process and slow down the spread of fire. Benzyl methyl(phenyl)phosphinate is also known for its low toxicity and environmental friendliness compared to other flame retardants, making it a preferred choice in many applications.

4126-92-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4126-92-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,1,2 and 6 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 4126-92:
(6*4)+(5*1)+(4*2)+(3*6)+(2*9)+(1*2)=75
75 % 10 = 5
So 4126-92-5 is a valid CAS Registry Number.

O-Phosphination of Aldehydes/Ketones toward Phosphoric Esters: Experimental and Mechanistic Studies

Qian, Yanyan,Dai, Qiang,Li, Zhiming,Liu, Yu,Zhang, Junliang

, p. 4742 - 4748 (2020)

Addition of P-H species to carbonyl groups, namely the Pudovik reaction, normally delivers hydroxyl phosphorus compounds, along with phosphate byproducts in some cases. A few controllable systems starting from phosphites were set up to mainly provide the phosphates. Herein, we present a highly selective protocol starting from phosphonate precursors leading to phosphinate derivatives. Enantioenriched phosphinates were successfully achieved from chiral phosphine oxide precursors. Experimental and theoretical investigations were conducted to understand the mechanistic details.
