Deeply Rooted in Heterocyclic Fine Chemicals, Ruiping Chemical Builds a Premium Raw Material Service Provider

In the Jintan District of Changzhou, Jiangsu Province, a chemical enterprise established over a decade ago — Changzhou Ruiping Chemical Co., Ltd. (brand WishChem, formerly Jintan Hope Chemical Co., Ltd.) — is steadily growing into a technological innovator in the fine chemical sector, leveraging its deep expertise in heterocyclic chemistry encompassing pyrimidines, indoles, triazines, and more.

Based in Changzhou, Building Momentum through Accumulated Strength

Changzhou Ruiping Chemical Co., Ltd. was founded in 2012, with its predecessor being the Sino-foreign joint venture Jintan Hope Chemical Co., Ltd. Located on Huacheng Road, Jintan District, Changzhou, the company owns standardized office and warehousing facilities and holds comprehensive qualifications including hazardous chemical operation permits, pesticide operation permits, and independent import/export rights. In 2024, the company established Jiangsu Zhirong Biotechnology R&D Co., Ltd. as an investment subsidiary, further expanding its R&D footprint. The company has obtained ISO9001 quality management system certification and has established a standardized product quality control system.

With over two decades of dedication to heterocyclic chemical R&D, the company has built professional R&D laboratories and partnered cooperative large-scale synthesis production bases, forming an integrated service model covering R&D, laboratory-scale trials, pilot-scale trials, and batch supply. The core management team has extensive experience in chemical foreign trade, with business covering all domestic provinces and municipalities, as well as exporting to Southeast Asia, Europe, and the Americas. The company offers one-stop supporting services including sample customization, batch custom manufacturing, and import/export solutions. Specializing in the distinctive heterocyclic niche of pyrimidines and indoles, the company holds independent synthesis patents and has developed over 100 fine chemical products, consistently supplying high-purity core intermediate raw materials to the agrochemical and pharmaceutical industries.

Distinctive Product Portfolio, Focused on Heterocyclic Chemistry

Ruiping Chemical is engaged in the research, development, production, and sales of pharmaceutical intermediates, agrochemical intermediates, and fine chemical products. Its core strength lies in its deep specialization in heterocyclic chemistry, with flagship product series covering pyrimidines, indoles, triazines, and naphthalenes, encompassing more than 100 product variants. Key products include 2,4-Dichloropyrimidine, 4,6-Dihydroxy-2-(methylthio)pyrimidine, and 6-Benzylaminopurine, among others, widely applied in high-end fields such as pharmaceutical synthesis, agrochemical innovation, and advanced material development.

The company's independently developed Trifludimoxazin (code HB002) is a novel pyrimidine salicylic acid-type herbicide with independent intellectual property rights, having been granted invention patents in both China and the United States. This product features high activity, low toxicity, non-residual properties, a broad herbicidal spectrum, and excellent crop safety for rice, making it a novel herbicide variety that aligns with the green and sustainable development requirements of modern agriculture.

1. Pyrimidine Series Agrochemical Intermediates (Core Flagship Products)
   Including foundational building blocks such as 4,6-Dimethoxypyrimidine, 2-Chloro-4,6-dimethoxypyrimidine, and 4,6-Dihydroxy-2-(methylthio)pyrimidine. Finished herbicide products include Propyl 4-[2-(4,6-dimethoxypyrimidin-2-yl)oxy]benzoate, Bispyribac-sodium, Pyriminobac-methyl, Pyribenzoxim, Halosulfuron-methyl, and Thiencarbazone-methyl, suitable for weed control in rice and rapeseed fields. The company is a core raw material supplier for mainstream herbicides in the domestic market.

2. Pharmaceutical Heterocyclic Intermediates
   Indole, triazine, naphthalene ring derivatives, and pyridine-substituted intermediates, including high-purity raw materials such as 2-Chloro-3-hydroxypyridine and multi-substituted halogenated pyrimidines. These products are used in the synthesis of anti-infective and chronic disease drugs, with controlled impurities and purity meeting pharmaceutical-grade standards.

Innovation-Driven, Industry-University-Research Collaboration

Guided by high-tech product development, Ruiping Chemical actively pursues an industry-university-research collaborative innovation model. The company maintains a deep partnership with the Yangtze River Delta Emerging Industry Cooperation Research Center of Changzhou University, jointly establishing the "Changzhou Ruiping Yangtze River Delta Green Innovation Joint Laboratory." Led by Professor Xu Defeng, the laboratory has designed and synthesized nearly 500 compounds, successfully screened 6 compounds with promising biological activity and novel chemical structures, filed 15 Chinese invention patents, 2 international patents, and 1 US patent, with 6 granted to date, and published nearly 20 research papers.

Actively responding to the national call for "self-reliance and self-strengthening in science and technology," Ruiping Chemical consistently adheres to the development philosophy of "innovation, green, and efficiency," continuously advancing the industrialization of green innovative technologies for pyrimidine series products. Looking ahead, the company will continue to optimize green synthesis processes, expand its high-purity pharmaceutical intermediate product lines, upgrade its digital service system, and leverage the WishChem brand to expand into global markets. Committed to becoming a world-leading professional service provider of heterocyclic fine intermediates, Ruiping Chemical aims to empower the high-quality development of the agrochemical and pharmaceutical industries.
