Yellow 150 is an organic pigment with the chemical name of diazaza 7-nitro-1,3-bisazine-4,6-dione. It is a yellow powder with good lightfastness, abrasion resistance and stability.

Yellow 150 is widely used in paints, inks, plastics, rubber and other fields. It can be used to color products to provide a brilliant yellow color. In addition, Yellow 150 can also be used for art and stationery purposes such as painting and rubber stamps.

There are two main ways to make yellow 150. One is to nitrate 1,3-bisazine-4,6-dione, then react it with sodium hydroxide, and finally filter, wash and dry to obtain yellow 150 pigment. Another method is through the Mannich reaction, that is, 1,3-bisazine-4,6-dione is added to nitric acid, and then it is heated, dissolved and filtrate treated with ammonia, and finally filtered, washed and dried to obtain yellow 150 pigment.
