HALO publishes batch-specific analytical documentation for qualified laboratory purchasers. Every active lot is tied to a certificate of analysis (COA) covering HPLC purity, identity confirmation, lot number, and test date. COAs ship with every order and are published on the corresponding product page as lots are released.
What each COA includes
- Compound name and SKU / vial size
- Lot / batch number (searchable)
- Test date and analytical method (HPLC, LC-MS/MS where applicable)
- Purity percentage and identity pass/fail
- Downloadable PDF certificate
How to verify a lot
Open the product listing for your compound and select View lab results or the COA block on the product page. Match the lot number on your vial label to the published batch record. For procurement files, retain the COA with your purchase order and receiving log.
