47369-00-6 Usage
General Description
1,1'-DIPHENYL-4,4'-BIPYRIDINIUM DICHLORIDE, also known as paraquat, is a highly toxic chemical compound commonly used as an herbicide. It is a non-selective herbicide, meaning it can kill a wide range of plants and plant parts with which it comes into contact. Paraquat is extremely poisonous to humans and animals, and if ingested, even in small amounts, can cause severe injury or death. Due to its high toxicity, paraquat is heavily regulated and its use is restricted in many countries. It is also known to be a potential health hazard as it can cause lung damage if inhaled and skin irritation if it comes into contact with the skin.
Check Digit Verification of cas no
The CAS Registry Mumber 47369-00-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,7,3,6 and 9 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 47369-00:
(7*4)+(6*7)+(5*3)+(4*6)+(3*9)+(2*0)+(1*0)=136
136 % 10 = 6
So 47369-00-6 is a valid CAS Registry Number.

A new class of light-fast oxonol dyes: Organic-glass forming salts of oxonol anions and 4,4′-bipyridinium cations

A new class of light-fast oxonol dyes were prepared. These dyes were spin-coated onto glass plates using 2,2,3,3-tetrafluoro-1-propanol as a solvent to form noncrystalline-solid-dye films. They were colored, transparent, uniform, but dark when placed between crossed polarizers. The change of the normalized absorbance of dye films measured at their respective absorption maxima. The oxidative quenching mechanism is responsible for the light-fastness of the oxonol salts. The heavy-metal free and organic recording dyes with enhanced light-resistance will expand the range of potential applications for oxonol dyes.
