Why Do Pharmaceutical Leaders Choose Kinso's APIs?

At Zhejiang Kinso Technology Co., Ltd., we know active pharmaceutical ingredients (APIs) aren't just chemicals—they're the foundation of life-changing medications. Our APIs are manufactured to meet the strictest global standards, ensuring purity and consistency in every batch for drug manufacturers worldwide.  

What Makes Our APIs Different?  

The difference is in our obsessive quality control. While others rush production, we take the time to perfect each step—from raw material selection to crystallization processes. I've reviewed competitors' certificates of analysis that show inconsistent potency, while our batches consistently hit 99.5%+ purity. Our state-of-the-art facility operates under cGMP guidelines, but what really sets us apart is our willingness to customize particle size and polymorphic forms to optimize your formulations.  

From antihypertensive intermediates to oncology APIs, we've earned the trust of generic and innovator companies alike. When your drug's efficacy depends on the API's quality, isn't it worth partnering with a supplier who treats each gram as potentially life-saving?
