Buyer Decision Guide
For this material the useful questions are about the dimer level and the storage history, not only the headline assay.
- Assay: 99.0% by HPLC on the isolated compound.
- Dimer content (diindolylmethane) reported per batch as a stability indicator.
- Identity confirmed against an I3C reference standard.
- Storage and transport conditions specified to limit acid-catalysed conversion.
- Residual solvents, loss on drying and heavy metals reported per batch.
- COA, specification sheet and safety data sheet accompany each shipment.
How This Grade Differs
Diindolylmethane (DIM) 99% is listed separately. It is a different compound from I3C, so compare chemical identity, assay and related-substance limits rather than treating the two products as interchangeable.
Related product: diindolylmethane (DIM) 99%. Confirm the current batch specification before substitution.
Quality and Documentation
Assay and dimer content are determined on the same HPLC run. Solvent residues, loss on drying and heavy metals are reported per lot, and storage conditions are recorded on dispatch.
