Jinan Zhihe Fine Chemical Co., Ltd. is a modern high-tech enterprise integrating the research and development, production, sales, and service of pharmaceutical and cosmetic raw materials. Adopting a diversified, light-asset development model that includes self-built factories, equity participation, leased factories, or contract manufacturing, the company has production bases in Jining, Dongying, and Heze, Shandong. For many years, the company has adhered to independent innovation and a development path that combines production, education, and research. Since its establishment, it has consistently upheld the principle of "quality, credibility, customer first, and mutual benefit," implementing a business philosophy that focuses on the present while looking toward the future. The company seeks survival through product quality, cooperation through integrity, and development through innovation. After years of development, the company's leading products are supported by strong technical capabilities, advanced production technology, and a robust quality assurance system. Grounded in technological research and development and fundamentally driven by customer needs, the company strictly adheres to product standards in production. Through robust technical support, it continuously provides high-quality raw materials to domestic and international pharmaceutical and cosmetic manufacturers, striving to offer accurate and effective solutions and technical services. With the principle of "mutual benefit and win-win," the company is committed to sincere cooperation and shared development. The company's advantageous products include the azelaic acid series and the hydrazide compound series. In the production, deep processing, and downstream derivation of the azelaic acid series, the company possesses strong technical advantages. Based on varying customer needs, azelaic acid has been developed into four categories: industrial grade, daily chemical grade, pharmaceutical grade, and derivative grade. Adhering to the philosophy of "either not doing it or doing it best," the company continuously improves the content of azelaic acid and various technical indicators, making its azelaic acid products industry-leading across all categories. In response to market demand and leveraging our technical reserves in azelaic acid, we have further developed downstream derivatives. Using our self-produced derivative-grade azelaic acid, we synthesize products such as azelaoyl chloride and potassium azeloyl diglycinate. Compared to industry peers, our products feature stable content, low chromaticity, neutral and stable pH, and can be directly used as raw materials in cosmetics. We offer various packaging specifications, from kilogram to tonnage levels, and provide micronization services to process powders of various particle sizes. In the hydrazide compound series, existing products include methyl carbazate, ethyl carbazate, tert-butyl carbazate, and acetylhydrazine. Through years of technical沉淀 and continuous improvement of process parameters, the product quality is now excellent. We will continue to increase R&D investment, improve processes, and enrich product varieties, working hand in hand to create a brilliant future.
