The company is located in the Ecological Industrial Park of Changshan County, with a registered capital of 10.5 million yuan and covers an area of 5,192.8 square meters. Currently, the company employs 178 staff, including 25 engineering technicians.

The company is a chemical enterprise primarily engaged in the production of dyes and pharmaceutical intermediates. In 2006, the company implemented a strategic transformation towards fine fluorine chemicals and adjusted its product structure. Currently, the company has production lines with an annual capacity of 4,000 tons of 2,4-dichlorofluorobenzene, 5,000 tons of nitrosyl sulfate, and 10,000 tons of potassium fluoride. In 2019 and 2020, the company achieved an industrial output value of 250 million yuan, generating over 60 million yuan in annual profits and taxes.

In recent years, the company has placed great emphasis on independent innovation and increased investment in technological capabilities. A new technology for "efficient fluorination production of 2,4-dichlorofluorobenzene from meta-oil" received provincial-level "New Product and New Technology Appraisal and Acceptance." In the same year, the project applied for a patent titled "Method for Comprehensive Utilization of Chloronitrobenzene Mixtures via Fluorination Reaction," obtaining an invention patent with fully independent intellectual property rights (Patent No. ZL200910100558.6). By the end of 2019, the company held 2 invention patents and 11 utility model patents.

In 2019, the company established a "Doctoral Workstation" and an "Academician Workstation," which are significant measures to further implement the principle that science and technology are the primary productive forces.
