Description
STANDARDISED BOTANICAL ACTIVE
Sulforaphane — Sulforaphane 1.0%
Sulforaphane is supplied as a standardised single-compound botanical active isolated from broccoli seed, released at Sulforaphane 1.0% by HPLC against a batch-specific certificate of analysis. The purchasing definition is the molecule and its declared purity rather than a plant-ratio extract, so the specification is agreed on assay, identity and impurity profile.

Buyer Decision Guide
Buyers approving Sulforaphane 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. Sulforaphane is offered at Sulforaphane 1.0% by HPLC. Confirm those three against your own specification so the delivered batch is released to the right grade.
- Assay: Sulforaphane 1.0% by HPLC, released against the batch COA.
- Identity: Sulforaphane 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
Sulforaphane 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 Sulforaphane is a single purified compound at Sulforaphane 1.0%. 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.

Frequently Asked Questions
What specification defines Sulforaphane Powder 1%?
For Sulforaphane Powder 1%: Sulforaphane 1.0%, tested by HPLC.
Which identity details must remain consistent?
For Sulforaphane Powder 1%: match Sulforaphane across the quotation, specification and offered-batch COA. The offered grade is Sulforaphane 1.0%.
How is batch-specific approval completed?
For Sulforaphane Powder 1%: the page cites representative batch LXLB260525. Final approval requires the current lot’s identity, specification results and relevant dates.
What forms part of the technical review?
For Sulforaphane Powder 1%: do not assess Sulforaphane 1.0% in isolation; particle size, moisture or drying data and market-relevant safety limits can also affect acceptance.
Are you a manufacturer or a trading company?
LongBio is Shaanxi Longsheng Biotechnology Co., Ltd., a direct manufacturer of botanical extracts and functional ingredients integrating R&D, production and export support. Factory review can be arranged by video or an on-site visit.
Can I request the current batch COA before ordering?
Yes. Request the applicable current or representative COA and compare product identity, method, limits and results before approving a purchase order.
What is the minimum order quantity?
The regular MOQ is typically 1 kg. An evaluation sample of 10-20 g can usually be arranged before a formal order, subject to stock.
Do you support custom specifications or packing?
Alternative assay targets, particle size, packing and private-label requirements can be reviewed case by case, subject to production feasibility and a revised written specification.
