Buyer Decision Guide
Vitamin grades are specified by potency, carrier and purity, and the same vitamin name can cover several physical forms. Confirm the exact form and the analytical method before comparing quotations; overage and stability requirements are project-specific.
- Confirm the exact physical form and carrier
- Check declared potency and the assay method
- Review stability and overage needs for your format
- Confirm light, heat and oxygen sensitivity in handling
How This Grade Differs
Folic Acid must be compared on physical form, carrier and declared potency rather than on the vitamin name alone. Powder, oil, crystal and diluted forms behave differently in blending, dosing and shelf life.
Compare these related grades before approval:
For a substitution review, compare folic acid identity, the 98.0%-101.0% HPLC assay on a dried basis, crystalline powder form and the current offered-batch COA.

Frequently Asked Questions
Can the COA be matched to the lot you ship?
Yes. The certificate is issued for the shipped lot, which is the batch LXYS260428 referenced on the specification.
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.
What purity window can you hold batch to batch?
98.0%-101.0% on dried basis, verified by HPLC on every lot.
How is appearance checked?
Fine yellow to orange-yellow crystalline powder, compared against a retained sample from the approved batch.
Which test method should our QC lab expect to reproduce?
HPLC, with the reference standard and calculation basis recorded on the batch certificate.
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.
Can I review the COA before I pay?
Yes. Request the current or representative COA and check identity, method, limits and results before approving the 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.
