31170-22-6 Usage
General Description
2-(prop-2-en-1-ylsulfanyl)pyrimidin-4(3H)-one, also known as TPO, is a synthetic compound and a widely used photoinitiator in the field of polymer chemistry. It is a yellowish crystalline solid that is insoluble in water, but soluble in organic solvents. TPO is commonly used in UV-curable coatings, inks, and adhesives to initiate the polymerization process when exposed to ultraviolet light. It is also used in the production of dental materials, electronics, and a variety of other industrial applications. TPO is known for its effectiveness in initiating rapid polymerization reactions and its low toxicity, making it a popular choice for a wide range of photopolymerization processes.
Check Digit Verification of cas no
The CAS Registry Mumber 31170-22-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,1,7 and 0 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 31170-22:
(7*3)+(6*1)+(5*1)+(4*7)+(3*0)+(2*2)+(1*2)=66
66 % 10 = 6
So 31170-22-6 is a valid CAS Registry Number.

IODOCYCLIZATION OF 2-ALLYLTHIO-4(3H)-PYRIMIDINONES
Kim, D. G.,Shmygarev, V. I.
, p. 183 - 185 (1995)
It has been established that the iodocyclization of 2-allylthio-4(3H)-pyrimidinones occurs at the N(1) nitrogen atom with the formation of 3-iodomethyl-7-oxo-2,3-dihydro-8H-thiazolopyrimidinium iodides and triiodides.
Palladium-Catalyzed Polyhetero-Claisen Rearrangement of 2-(Allylthio)pyrimidin-4(3H)-ones

, p. 764 - 768 (2007/10/02)
The regioselective S -> N allylic transposition of 2-(allylthio)pyrimidin-4(3H)-ones (3) has been performed by catalysis of Pd(II) salts.Generally the rearrangement gives the N-1 alkylation product predominantly over the N-3-alkylation product.Substituents at the 6-position of 3 reverse the selectivity.Both N-1 and N-3 rearrangement products were transformed to thiazolopyrimidones.
