CDMO For Fine Chemicals

Continuous Flow Reaction Technology – The Innovation Engine for Pesticide and Dye Intermediate CDMO Processes

Continuous flow reaction technology, with its core advantages of efficiency, safety, and sustainability, is reshaping the production model for pesticide and dye intermediates. As a leading CDMO in the pharmaceutical and chemical sectors, we apply this technology in Continuous flow synthesis of pesticides and Continuous flow dye intermediate production, providing global customers with high-purity, low-cost, customized solutions.

Core Advantages of Continuous Flow Processes: Dual Breakthroughs in Efficiency and Safety

Pesticide Intermediates: Efficient Synthesis of Fipronil

Process Challenge Breakthrough: To address the challenges of the sensitivity of active groups in Fipronil intermediates and the high hydrogenation risks, we use micro-channel continuous flow reactors:

Hydrogenation Reduction: Catalytic hydrogenation is completed under 0.5MPa low pressure, reducing reaction time to 1/3 of traditional processes and increasing yield by 20%.

Fluorination Reaction: An integrated online monitoring system is used to control the fluorinating reagent flow rate in real-time, preventing by-product formation, achieving purity ≥ 98%.

Green Recovery: By-products are purified through membrane separation and reused, reducing solvent consumption by 30%, aligning with the trend of Green chemical processes in agrochemicals.

Dye Intermediates: Precise Synthesis of Azo Compounds

Process Upgrade: Using Continuous flow reaction for azo dye intermediates as an example:

Diazotization-Coupling Integration: Hydroquinone and β-naphthol continuously react in a microreactor at 0-5°C to avoid diazonium salt decomposition, with color deviation < 5%.

Color Stability: The continuous flow process eliminates batch differences, with azo dye intermediates having purity ≥ 98%, suitable for high-end textile printing and dyeing needs.

Zero Waste Liquid Emission: By-products are recovered and reused after acid precipitation, in compliance with REACH regulations.

CDMO Full-Chain Services: From Process Development to Scalable Production

Technical Customization and Rapid Scale-up

Process Design: Customizing reactor types (plate/tube) and parameters (flow rate, temperature) according to the characteristics of high-purity pesticide intermediates or dye intermediates.

Safety Empowerment: By leveraging the safety benefits of continuous flow in chemical synthesis, we avoid the risk of bulk storage for hazardous intermediates (e.g., isocyanates).

Compliance and Quality System

Analytical Method Development: Using HPLC and GC-MS to monitor impurity profiles, ensuring products meet FDA/EPA standards.

Global Registration Support: Providing environmental impact assessments for continuous flow in agrochemical manufacturing, accelerating customer product registration.
