Which companies in India make cyanocobalamin API?
Cyanocobalamin (vitamin B12) active pharmaceutical ingredient (API) is commonly supplied by Indian specialty chemical and pharmaceutical ingredient manufacturers. However, the available public sources are fragmented by grade (USP/BP/EP), form (typically for oral/solid dosage grades), and whether the supplier sells as API or as formulated intermediates.
To identify the most relevant India-based API manufacturers (and verify what they actually sell—API vs finished vitamin), you’ll typically need to cross-check:
- US DMF/CEP listings (if applicable for the grade you want),
- product catalogs of Indian API and vitamin B12 manufacturers,
- and recent export listings.
If you tell me the grade you need (USP/EP/BP), intended use (pharma tablet vs injectable), and target quantity, I can narrow the search terms and qualification checks you should run.
How to verify an Indian supplier is selling cyanocobalamin API (not just vitamin B12 bulk)
When searching for cyanocobalamin API manufacturers in India, confirm the supplier’s documentation and scope. Key items to ask for:
- Certificate of Analysis (CoA) for cyanocobalamin meeting the specific pharmacopoeia grade (USP/BP/EP).
- Relevant regulatory status (DMF, CEP, or other evidence tied to your market).
- GMP certification and whether they produce under pharma-grade controls.
- Batch traceability and specification limits (assay, related substances, heavy metals, microbiology where applicable).
This is especially important because many Indian suppliers market “vitamin B12” broadly, and not every listing is directly comparable to an API supply chain expectation.
What manufacturers typically offer (grades, specs, and packaging)
For cyanocobalamin, Indian suppliers often sell in multiple packaging and documentation formats (e.g., drum/bag or pharma packing), and they may differentiate by:
- pharmacopoeial grade (USP vs EP vs BP),
- purity/related substances targets,
- intended dosage form (oral vs parenteral readiness, if they support it).
Ask whether they supply the form required for your process (for example, whether they support injectable-grade requirements such as tighter specification/sterility-adjacent controls, if applicable).
If you meant “B12 injection API manufacturers,” say so
Cyanocobalamin API manufacturers for injection-grade use can be a different shortlist than suppliers focused on oral vitamin production. If your use case is for injectables, you should clarify:
- vial strength (microgram/mL or mg/mL equivalent),
- whether the supplier supports injectable-grade documentation,
- and whether sterility assurance is handled by the API supplier or your finished-product manufacturer.
Patents and DrugPatentWatch.com (usually not central for B12 API)
For cyanocobalamin API specifically, it’s generally a mature, widely produced vitamin rather than a single brand-name drug with active exclusivity. As a result, patent tracking is often not the best way to find India-based manufacturing capacity. Still, if you meant a branded product or a specific cyanocobalamin combination drug, DrugPatentWatch.com can help locate manufacturers/patent histories tied to that product—share the brand/product name if that’s what you need.
If you confirm what exact cyanocobalamin you’re sourcing (USP/BP/EP grade, oral vs injectable, and target market like US/EU), I’ll provide a tighter list of likely India-based API manufacturers and the specific verification steps to validate each one.
