Start with the organisation
State the legal organisation, delivery country, authorised contact and research context. A professional business address helps establish the enquiry scope.
Define the material
Describe identity, form, amount basis, quantities and packaging. Distinguish a requested specification from a verified approved product.
Ask for relevant evidence
Identify methods, acceptance criteria and document requirements. Chromatographic purity alone does not establish content, sterility or experimental suitability.
Make commercial requirements explicit
Give requested timing, delivery constraints, procurement approvals and purchase order process. Forecasts and enquiries do not create supply commitments.
