12671-74-8 Usage
Description
Solvent Yellow 98 is an organic dye that is characterized by its yellow-orange powder form. It is insoluble in water but easily soluble in organic solvents. This product is known for its beautiful fluorescence, good light resistance, and good thermal fastness.
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.
