2898-84-2 Usage

Vibrant red color

The presence of the azo group and the pyrazolone group results in a strong red hue.

Check Digit Verification of cas no

The CAS Registry Mumber 2898-84-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,9 and 8 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 2898-84:
(6*2)+(5*8)+(4*9)+(3*8)+(2*8)+(1*4)=132
132 % 10 = 2
So 2898-84-2 is a valid CAS Registry Number.

The synthesis and characterizations of thermally-stable yellow metal complex dyes for LCD color filters

Lee, Jae-Yong,Kim, Ji-Hye,Bae, Ji-Hye,Yoon, Chun,Kim, Jae-Pil,Choi, Jae-Hong

, p. 60 - 69 (2014/01/17)

Eight kinds of yellow metal (III) complex azo dyes were synthesized using different diazo component, coupling component and metal ion. The effect on the thermal stability of the synthesized dyes by azo ligand with two different functional groups, alcohol and carboxylic acid, was studied. The characteristics of the synthesized dyes were examined by their absorption maxima, thermal stability by a thermogravimetric analysis (TGA), and the chromatic characteristics of the fabricated films were measured. It was also explained that the effect of functional groups on the thermal stability of the dyes as well as their chromaticity values. Copyright Taylor and Francis Group, LLC.
