01
Use CAS and purity target as the RFQ anchor
Supplier matching should begin with CAS number, target purity, assay method, impurity profile and intended use case.
02
Separate sample, validation and recurring demand
Pilot quantity, validation batch and annual demand require different price, packaging and documentation assumptions.
03
Request export and safety documents early
MSDS, COA, export classification and shipping route constraints should be reviewed before final supplier selection.
