2. core application areas

1. Dye industry:

As ice dye red base GG(C.I. Azoic Diazo Component 3), it is used for dyeing and printing cotton fabric, viscose fiber, silk and nylon.

Coupling with chromophone can generate a variety of colors such as big red, yellow, etc., with strong coupling ability and fast speed.

Used in the synthesis of 2,5-dichloroaniline -4-sulfonic acid and other organic pigment intermediates.

2. Pesticide industry:

A key intermediate in the synthesis of the herbicide dicamba (Dicamba).

3. Other areas:

Manufacture of nitrogen fertilizer synergists (e. g. N-2, 5-dichlorophenylsuccinamic acid).

Laboratory used as gas chromatography contrast samples or analytical reagents.
