How to specify Pterostilbene
Reference CAS 537-42-8 in your enquiry and state the intended application, required grade, assay or concentration, physical form, quantity, packaging and delivery destination. Specify hydration state or stereochemical form where relevant. A database identity does not establish the composition, quality or suitability of a commercial batch.
Documents and supply qualification
Request the supplier’s current Safety Data Sheet (SDS), a grade-specific Technical Data Sheet (TDS) and a batch-specific Certificate of Analysis (COA). Confirm acceptance criteria and test methods before ordering. Price, availability, lead time, origin, packaging and any applicable transport or destination restrictions must be confirmed against the enquiry.
Food, cosmetic or other regulated use requires separate review of the offered grade and destination requirements. No certification, regulatory approval or fitness for a particular use is claimed by this identity record.
Identity source
Database identity checked on against PubChem, CID 5281727. The check matched the CAS synonym to the compound record and retrieved formula and molecular weight. It is not a laboratory test, supplier audit or expert compliance review.
