12671-74-8 Usage
Uses
Used in the Plastics Industry:
Solvent Yellow 98 is used as a coloring agent for polymethyl methacrylate, polystyrene, and polyester plastic. Its properties, such as good light resistance and thermal fastness, make it suitable for these applications.
Used in 3D Printing:
Solvent Yellow 98 is also used as a component of photopolymer resins for luminescent three-dimensional printing, taking advantage of its fluorescent properties.
Standard:
The light fastness of Solvent Yellow 98 is rated as ISO 7, and it has a heat resistance of 105°C. It is stable in water, sodium carbonate (5%), and hydrochloric acid (5%). The melting point of Solvent Yellow 98 is stable.
Preparation
4-Nitro[1.8]naphthalic anhydride with 2-Aminobenzenethiol?etherification, with Octadecanamine and amination, with Sodium nitrite diazotization, with Copper sulfate monohydrate closed loop, and then soda boiling.

Check Digit Verification of cas no
The CAS Registry Mumber 12671-74-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,6,7 and 1 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 12671-74:
(7*1)+(6*2)+(5*6)+(4*7)+(3*1)+(2*7)+(1*4)=98
98 % 10 = 8
So 12671-74-8 is a valid CAS Registry Number.
