218608-69-6 Usage
General Description
2,3-Dihydro-2,2,5-tribromo-1H-inden-1-one is a chemical compound that is primarily used as a flame retardant and as an intermediate in the synthesis of other organic compounds. It is a white to off-white crystalline solid and is insoluble in water, but soluble in organic solvents. 2,3-DIHYDRO-2,2,5-TRIBROMO-1H-INDEN-1-ONE is known for its ability to inhibit the combustion process by releasing bromine radicals that interrupt the chain reaction of fire. It is commonly used in the production of plastics, textiles, and other materials that require flame resistance. However, it is important to handle this compound with care, as it is toxic and can cause irritation to the skin, eyes, and respiratory system if not used properly.
Check Digit Verification of cas no
The CAS Registry Mumber 218608-69-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,8,6,0 and 8 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 218608-69:
(8*2)+(7*1)+(6*8)+(5*6)+(4*0)+(3*8)+(2*6)+(1*9)=146
146 % 10 = 6
So 218608-69-6 is a valid CAS Registry Number.

PPh3·HBr-DMSO: A Reagent System for Diverse Chemoselective Transformations
Mal, Kanchan,Kaur, Amanpreet,Haque, Fazle,Das, Indrajit
, p. 6400 - 6410 (2015/06/30)
The broad applicability of the hitherto unexplored reagent combination PPh3·HBr-DMSO is exemplified with multiple highly diverse one-step transformations to synthetically useful building blocks, such as flavones, 4H-thiochromen-4-ones, α-hydroxy ketones, 1,4-naphthoquinones (including vitamin K3), 2-bromo-3-substituted-1H-1-indenones, 2-methylthio-1H-1-indenones, 3-butyne-1,2-dione, and 4-pentene-2,3-diones. The simple and mild reaction conditions make the reagent superior in terms of yield and substrate scope in comparison with the existing alternatives.
