Used in Epoxy Resin Curing:
Tris(2-cyanoethyl)phosphine oxide is employed as a curing agent for epoxy resins, facilitating the hardening process and resulting in strong, thermoset polymers that are resistant to heat and chemicals.
Used as a Stabilizer in PVC Formulations:
tris(2-cyanoethyl)phosphine oxide also functions as a stabilizer in polyvinyl chloride (PVC) formulations, preventing degradation and maintaining the material's flexibility and durability over time.
Used in Pharmaceutical and Agrochemical Synthesis:
Tris(2-cyanoethyl)phosphine oxide finds application in the synthesis of various pharmaceuticals and agrochemicals, where its unique properties contribute to the development of new and effective products.
However, it is important to handle tris(2-cyanoethyl)phosphine oxide with care due to its toxic nature and potential to cause irritation to the skin, eyes, and respiratory system.
Check Digit Verification of cas no
The CAS Registry Mumber 1439-41-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,3 and 9 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1439-41:
(6*1)+(5*4)+(4*3)+(3*9)+(2*4)+(1*1)=74
74 % 10 = 4
So 1439-41-4 is a valid CAS Registry Number.

The reaction of 6-bromo-1,2-naphthoquinone with tri(2-cyanoethyl)phosphine or tricyclohexylphosphine leads to the unusual formation of 6,6'-dibromo-1,1',2,2'-tetrahydroxy-4,4'-binaphthyl; its structure was confirmed by NMR spectroscopy and single crystal
Alkylation of phosphine PH3 generated from red phosphorus

, p. 3297 - 3300 (2007/10/02)
The generation of phosphine PH3 by alkaline hydrolysis of red phosphorus is realized. The subsequent alkylation of PH3 by terminal alkenes and alkynes in basic media leading to the corresponding aliphatic and vinylic phosphine derivatives can occur by two-steps or one-pot reaction by a Michael-like reaction mechanism.
