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.
5,7-Dimethoxyflavone is listed as in-stock / available for research-use sourcing review. Final availability, lot specification, and lead time are confirmed by RFQ.
The page shows a public reference price in the quote panel. Submit an RFQ to confirm current price, quantity breaks, lead time, and destination-specific shipping requirements.
Yes. Supplier-issued COA and SDS can be requested during the RFQ workflow. Lot-specific documents depend on supplier and batch confirmation.
