1. Naphthoquinone Series Intermediates

• 2-Chloro-1,4-naphthoquinone and 2,3-Dichloro-1,4-naphthoquinone — critical raw materials for antimalarial and anti-infective drugs like Atovaquone and Buparvaquone. Produced at a hundred-ton scale annually, these are among the company's dominant products in the domestic market. As an important dye and pesticide intermediate, 2-chloro-1,4-naphthoquinone is used to synthesize various high-performance disperse dyes and fungicides. This product is one of the company's core strengths, benefiting from mature processes and stable quality.

2. D-Ring (Cyclopentanedione) Series

• 2-Ethyl-1,3-cyclopentanedione and 2-Methyl-1,3-cyclopentanedione — key synthetic precursors for the steroid drug Levonorgestrel. The company has mastered mature processes and stringent impurity control for these products.

3. Tetralone Series

• 6-Methoxy-1-tetralone, 6-Hydroxy-1-tetralone, and 6-Benzyloxy-1-tetralone — widely used in the synthesis of anti-tumor and hormonal APIs. Among these, 6-methoxy-1-tetralone is a key pharmaceutical intermediate and a core advantageous product of the company. It is primarily used to synthesize non-steroidal anti-inflammatory drugs (e.g., Naproxen) and other chiral drugs. Chutian Fine has accumulated extensive technical expertise in the industrial production of this compound.

4. Pesticide Intermediates

• Pyrazosulfuron-ethyl amine (an intermediate for Pyrazosulfuron-ethyl) and 2-Aminothiazole — suitable for the synthesis routes of various herbicides and fungicides. 2-Aminothiazole is an important nitrogen-containing heterocyclic intermediate and another core product for the company. It is widely applied in the synthesis of pharmaceuticals (e.g., Sulfathiazole, anti-HIV drugs) and pesticides (e.g., thiazole fungicides and herbicides), offering broad market prospects.

5. Other Fine Intermediates

• 4-(4-Chlorophenyl)cyclohexanecarboxylic acid, 2,7-Dichlorofluorene, 2,7-Dihydroxy-9-fluorenone, etc. The company also undertakes custom synthesis and development projects.

• Disperse Blue 360: A high-performance anthraquinone disperse dye and a core product for the company. It exhibits excellent light fastness, sublimation fastness, and brilliant color, making it widely used in high-temperature, high-pressure dyeing of polyester and its blended fabrics.
