Description
HIGH-PURITY SPECIALTY INGREDIENT
PQQ Disodium Salt (Pyrroloquinoline quinone disodium salt)
PQQ disodium salt (pyrroloquinoline quinone disodium salt) is supplied at 99.0% as a high-purity B2B raw material. It is available from both synthetic and fermentation routes; the route for the offered batch is stated on the COA because the two differ in impurity profile and in the residual solvent picture, which matters for some approval dossiers. Handle protected from light and moisture. This material is not a finished consumer product.

Buyer Decision Guide
Buyers approving PQQ Disodium Salt (Pyrroloquinoline quinone disodium salt) normally agree four points before the first order: the assay method and acceptance range, the identity and isomeric form, the residual solvent limits applicable to the destination market, and the physical form required by the buyer’s process. Confirm these at enquiry stage so the shipment is released to the right specification.
- Assay: 99.0% by HPLC, released batch by batch against the current COA.
- Identity: confirmed by the analytical methods stated in the specification table above.
- Residual solvents and heavy metals: reported per batch and reviewed against the destination market’s limits.
- Physical form: powder as standard; packaging and particle size agreed against the buyer’s process.
- Documentation: COA, specification sheet and safety data sheet accompany each shipment.
- Regulatory status, permitted uses and labelling requirements are the buyer’s responsibility for the destination market.
How This Grade Differs
PQQ Disodium Salt (Pyrroloquinoline quinone disodium salt) is often quoted alongside materials of the same or a closely related name at a different purity or in a different form. The two are not interchangeable: purity, residual solvent profile and physical form all change the buyer’s processing yield. Compare quotations on the released assay and the reported impurity profile, not on the headline percentage alone.

For a substitution review, compare botanical identity, plant part, assay target, analytical method, physical form and the current offered-batch COA.

Frequently Asked Questions
How should the material be stored after arrival?
Two years when stored properly. Keep the pack sealed; moisture uptake is the main risk for this grade.
How does the material behave in your process?
It is supplied as Fine dark red to brownish-red crystalline powder at 98% through 80 mesh, so bulk density and flow are confirmed against your process before the first order.
What do you declare for moisture and ash?
Both are released against the limits on the approved specification; the measured result for your lot appears on its COA.
How recent is the representative batch shown?
The batch referenced is LXGZ260413; your shipment is released on its own certificate rather than the representative one.
Which test method should our QC lab expect to reproduce?
HPLC, with the reference standard and calculation basis recorded on the batch certificate.
How is the material shipped?
Air and sea freight are both arranged, with the mode chosen against volume, destination and required date. Documents and the HS code are issued with the shipping instructions.
What is the usual lead time?
Regular production normally takes 7-15 working days after deposit, depending on stock, volume, testing and customisation requirements.
Can you produce to our own specification or packing?
Alternative assay targets, particle size, packing and private-label requirements are reviewed case by case, subject to production feasibility and a revised written specification.
