 Custom chemicals
LONGCHEM specializes in R & D and custom manufacturing of various intermediates and fine chemicals. We are good at project management.
Based on our rich experience and solid background, we offer a wide range of chemical manufacturing technologies to our customers. The technologies can be either transferred by our customers or be developed by in-house R & D centers, which are overall more than 1000SQM.
Custom manufacturing are always proceeded under confidential disclosure agreements. Custom manufactured products are solely sold to the specific customer. The right of intellectual property will be discussed in the CDA. All R & D track records are traceable as per the established SOP from lab scale to trial production via pilot production.
Impurity profile will be synthesized during the developing process. Residual solvents will be tested before scale-up.
We succeed in most of challenges from our partners as we integrate our resources among Organic Chemistry, Chemical Engineering, Pharmacology, and International business with respectful working experiences.
Such background of working team possess sufficient ability to combine in-house technology with outdoor strengths to fulfill sophisticated challenges.
