CDMO

LONGCHEM specializes in R & D and custom manufacturing of various intermediates and fine chemicals.  We are good at project management.


Based on our evolving solid database, we can offer a wide range of  heterocyclic compounds (such as pyridine, pyrimidine, pyrrole, pyrazole) to our customers. The technical process can be either transferred by our customers through Tech Package or be developed by our in-house R & D center, which are > 1000SQM.


Custom manufacturing is always proceeded under confidential disclosure agreements. Custom manufactured products are solely sold to the specific customer. The right of intellectual property will be covered in the CDA. All R & D track records are traceable as per the established SOP from lab scale to trial production via pilot production. EHS and quality experts will always get involved from the beginning of the project so as to make sure the project developed or conducted could be commercialized safely and environment-friendly.


Impurity profile will be studied, impurities will be synthesized and controlled during the developing process. Residual solvents will be regulated at each scale to meet the requirement for the quality risk management.


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.


The competence of our integrated team to combine in-house core technologies with contract labs to fulfill sophisticated challenges help us earn our reputation in this pharmaceutical industry.
