Formulation development
Assess the API in the intended dosage form, using qualified development material and a defined specification.
Manufacturing qualification
Review the source, analytical methods and batch documentation before commercial process qualification.
Procurement evaluation
Send your target specification, quantity and destination so SBS can review a suitable sourcing proposal.
Identity, physical grade and specification
| Selection point | Material / requirement | Buyer review |
|---|---|---|
| Chemical identity | Phosphated vitamin B₂ salt | Confirm the exact salt or hydrate in the purchase specification. |
| Physical grade | Particle distribution and bulk characteristics | Agree measurable limits and test methods for the intended process. |
| Quality standard | Required pharmacopoeia or agreed specification | Review the current specification, COA and supporting documentation. |
Formulation & processing
Product-specific considerations
Review light protection, particularly for solutions, and moisture control during handling. Do not treat a riboflavin-equivalent assay as a direct percentage of the complete sodium salt.
Batch calculations
Use the stated assay basis and current batch results in the approved manufacturing calculation. Distinguish salt or hydrate mass from equivalent active content.
Process suitability
Confirm compatibility and finished-product quality in the complete formulation; a material name or assay result alone does not establish process suitability.
What to check in the specification
- Identity of the active ingredient, salt and hydration state
- Assay method and calculation basis
- Specified, unspecified and total related substances
- Water or loss on drying and residual solvents
- Particle characteristics and microbiological requirements appropriate to the process
Current product documentation
Request the current batch COA, complete specification, SDS and stability/retest information. Discuss manufacturer qualification and applicable regulatory-support documents for your intended market.

Packing and quotation details
Confirm pack size, inner liner, container type, batch traceability, quantity and delivery terms with the quotation. No standard pack size or stock availability is implied.
Storage and safe handling
Keep the original container closed and protected from contamination. Follow the manufacturer’s labelled storage conditions, retest date and SDS; agree additional light or moisture protection where required.
Frequently asked questions
What should an enquiry include?
Required grade, dosage form, specification, quantity and delivery destination.
Are specifications and documents available?
Request the current batch COA, complete specification, SDS and stability/retest information. Discuss manufacturer qualification and applicable regulatory-support documents for your intended market.
Is the supplied API automatically suitable for every dosage form?
No. Suitability depends on the offered grade, impurity and microbiological controls, intended route and validated manufacturing process.
