Furfuryltriphenylphosphonium chloride (FTPPC) is a phosphonium salt with the chemical formula C25H22ClOP. It is a colorless to pale yellow crystalline solid, soluble in organic solvents such as ethanol, acetone, and dichloromethane. FTPPC is synthesized by the reaction of furfuryl chloride with triphenylphosphine, and it is used as a phase-transfer catalyst in various organic reactions, particularly in the synthesis of fine chemicals and pharmaceuticals. It is also employed in the preparation of other organophosphorus compounds and as a reagent in the Wittig reaction. Due to its stability and selectivity, FTPPC has gained significant attention in the field of organic chemistry.

Check Digit Verification of cas no

The CAS Registry Mumber 3729-99-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,7,2 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 3729-99:
(6*3)+(5*7)+(4*2)+(3*9)+(2*9)+(1*9)=115
115 % 10 = 5
So 3729-99-5 is a valid CAS Registry Number.

Synthesis of aryl and heterocyclic polyenes and their activity in free radical scavenging

Deng, Kaini,Yang, Zuxing,Luo, Juan,Wu, Kaiqun

, p. 129 - 132 (2018)

Aryl polyenes and heterocyclic polyenes with the same central C20 unit of β,β-carotene but different terminal groups were synthesised. Their free radical scavenging activity was measured by a 1,1-diphenyl-2-picrylhydrazinyl spectrophotometric method. The results indicated that all the new compounds have free radical scavenging activity.
