446-55-9 Usage
General Description
FAST SCARLET TR-SALT, also known as the sodium salt of the azo dye C.I. Pigment Red 3, is a bright red pigment widely used in industrial applications such as textiles, plastics, and printing inks. It is a water-insoluble powder that is typically dispersed in solvents or resins before being used. As a pigment, FAST SCARLET TR-SALT provides strong, vibrant coloration and has good lightfastness and heat resistance. It is also known for its high tinting strength, meaning it can be used in small quantities to achieve intense coloration. In addition to its use as a pigment, FAST SCARLET TR-SALT has also been studied for its potential use in medicine and biotechnology.
Check Digit Verification of cas no
The CAS Registry Mumber 446-55-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,4 and 6 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 446-55:
(5*4)+(4*4)+(3*6)+(2*5)+(1*5)=69
69 % 10 = 9
So 446-55-9 is a valid CAS Registry Number.

Dual palladium-photoredox catalyzed chemoselective C-H arylation of phenylureas
Babu, Sakamuri Sarath,Shahid,Gopinath, Purushothaman
, p. 5985 - 5988 (2020)
A highly chemoselective C-H arylation of phenylureas has been accomplished using dual palladium-photoredox catalysis at room temperature without any additives, base or external oxidants. Regioselective C-H arylation ofN,N'-diaryl substituted unsymmetrical phenylureas has also been accomplished by a careful choice of aryl groups.
