Description
STANDARDISED BOTANICAL ACTIVE
Caffeic acid — 98.0%
Caffeic acid is supplied as a standardised single phenolic acid at 98.0% by HPLC, released against a batch-specific certificate of analysis. It is offered in the free-acid form; salts and esters of the same acid are separate products with different solubility and are not interchangeable. The purchasing definition is the molecule and its declared purity rather than a plant-ratio extract.

Buyer Decision Guide
Buyers approving Caffeic acid usually settle three points before the first order: the assay method and acceptance range, the identity of the compound as distinct from a same-named plant extract, and the physical form the buyer’s process needs. Caffeic acid is offered at 98.0% by HPLC. Confirm those three against your own specification so the delivered batch is released to the right grade.
- Assay: 98.0% by HPLC, released against the batch COA.
- Identity: Caffeic acid as a single compound, not a plant-ratio extract.
- Impurity profile and residual solvents reported per batch.
- Physical form and particle size agreed against the buyer’s process.
- COA, specification sheet and safety data sheet accompany each shipment.
- Regulatory status, permitted uses and labelling are the buyer’s responsibility for the destination market.
How This Grade Differs
Caffeic acid is frequently quoted alongside a botanical extract of the same plant. The extract is standardised to a ratio or to a minimum marker content, while Caffeic acid is a single purified compound at 98.0%. The two are not interchangeable: dosing calculations, solubility and the analytical method used to release them all differ. Compare quotations on the declared assay and method, not on the plant name.
For a substitution review, compare botanical identity, plant part, assay target, analytical method, physical form and the current offered-batch COA.
