Answer: Describe each modification, position, salt or counter-ion and analytical need.
What to define
Start with the precise sequence or product identity, intended application, requested quality attributes, quantity, packaging and destination market. State which details are requirements and which are preferences. For transferred or repeat work, include relevant process history and analytical information under appropriate confidentiality controls.
What the quotation should make clear
A useful proposal identifies scope, customer inputs, technical assumptions, deliverables, review gates, schedule basis and exclusions. It should distinguish development work from routine manufacturing and explain when specification, method or scale changes require another review.
Quality and documentation
Certificate claims do not replace product and batch evidence. Review applicable ISO 9001, ISO 22000, HACCP or GMP certificate scope as part of qualification, then agree on product-specific methods, acceptance criteria, COA, SDS, traceability and release documents.
Next step
Use the project RFQ form or browse the product catalog. Include the keyword context “modified peptide synthesis” only when it accurately describes the required service.
