FAQ
Frequently asked questions
What is the difference between GMP and non-GMP intermediates?
Intermediates used in the final GMP synthesis steps are produced under ICH Q7 GMP controls, while early-stage intermediates follow ISO quality systems; we clearly document which standard applies to each product.
Do you offer custom synthesis of intermediates?
Yes, from route development and lab-scale feasibility through pilot and commercial supply, with full confidentiality agreements.
How do you protect intellectual property?
We sign customer-specific NDAs, keep dedicated production records, and never market customer-designed molecules to third parties.
What analytical documentation accompanies each batch?
Each batch is delivered with COA (HPLC/GC assay and purity), NMR and MS structural confirmation, residual solvent data per ICH Q3C and impurity profile per ICH Q3A/B.
Can you scale from gram quantities to multi-ton production?
Our partner plants cover kilo-lab, pilot and multi-ton capacity, so the same validated route can scale with your programme.
What purity can you guarantee for intermediates?
Standard specification is 97-99% HPLC purity with individually agreed limits for single unknown impurities and genotoxic impurities per ICH M7.
What is the minimum order quantity?
Gram to kilogram quantities for development, and 25 kg drums upward for commercial supply; MOQ is agreed per product.
What is the typical lead time?
Stocked intermediates ship in 1-2 weeks; custom synthesis typically takes 4-12 weeks depending on route complexity and scale.
Can you supply impurity reference standards?
We can isolate, characterize and supply process-related impurities as qualified reference standards for your analytical method validation.
What packaging is used for intermediates?
Development quantities in sealed poly bottles, commercial quantities in 25 kg fibre drums or as agreed; temperature-sensitive products ship with cold packs.
