Procurement notes
MolGraph uses public price and availability evidence as a starting point, then confirms current stock, quotation, COA/SDS, lot specification, lead time, and shipment documentation before final acceptance.
Use the quote panel for visible public options. Additional quantities or specifications can be reviewed by RFQ.
Purity, lot identity, and batch-specific documentation are confirmed before procurement decisions.
Supplier-issued COA and SDS can be requested before handling, storage, shipment, or procurement decisions.
Final quote depends on quantity, lead time, destination, and supplier confirmation.
