Zibo Jingding Chemical New Material Co., Ltd. was established in April 2011 and is located in the Polymer Additives Industrial Park of Zibo High-tech Industrial Development Zone. This zone is one of the 53 national high-tech industrial development zones approved by the State Council in November 1992 and has been designated by the Ministry of Science and Technology as a national new materials industrialization base. Our company enjoys a superior geographical location with excellent transportation access. It is 4 kilometers from the Qingyin Expressway, 80 kilometers from Jinan International Airport, 210 kilometers from Qingdao International Airport, and 220 kilometers from Qingdao Port. The company originated from Zibo Zichuan Xingyue Chemical Plant and is a specialized fine chemical enterprise integrating production, supply, sales, and research. Currently, the company employs 30 staff members, having cultivated a stable and skilled workforce over the years, including 2 senior engineers and 6 intermediate technicians. We maintain long-term collaborations with Tianjin University and Xinhua Research Institute, providing us with strong technical capabilities. The company's designed annual production capacity is 600 tons/year, with an actual output of 300 tons/year in 2015 and an annual output value exceeding 30 million RMB. We specialize in the production of phosphonium salt series products, mainly including Methoxymethyltriphenylphosphonium Chloride (AWS), Methyltriphenylphosphonium Bromide (BWS), and Ethyltriphenylphosphonium Bromide (CWS). These products are primarily used in high-end liquid crystal products and pharmaceutical synthesis (such as precursor substances for Wittig reagents, used for the methoxymethylation of carbonyl compounds, e.g., in the synthesis of steroids and prostaglandin analogs).
