API intermediates
API intermediates and key starting materials produced by custom synthesis to the customer's route and specification, from gram-scale trials to commercial campaigns.
Many pharmaceutical companies outsource the earlier steps of a synthesis — key starting materials and advanced intermediates — so their own plants can focus on the regulated final API steps. Custom synthesis means producing those molecules to the customer's route, specification and impurity profile.
Projects typically move from technology transfer and laboratory validation to pilot batches and then commercial campaigns. Work is carried out under NDA from first contact, with analytical methods agreed up front and impurity, residual solvent and assay data supplied with each batch.

API intermediates — frequently asked
To quote for a custom intermediate, share the structure, the preferred route (if any), the target specification and impurity limits, annual volume and timeline. All information is handled under a non-disclosure agreement.
An NDA is signed before any technical discussion. The customer's route, process parameters and specification remain their property and are not used for other customers or products.
Yes. Projects start with laboratory validation and pilot batches, then scale to commercial campaigns once the process and specification are confirmed.
Yes. Chemtrade manufactures and exports API intermediates from Surat, Gujarat, India to more than 55 countries, for customers in Pharma. Send your grade, quantity and destination port for a quotation within one business day.
Every shipment of API intermediates from Chemtrade includes a batch-specific Certificate of Analysis (COA) and Material Safety Data Sheet (MSDS). Certificate of Origin, third-party pre-shipment inspection and destination-specific regulatory documentation are arranged on request.
