Which Indian companies make flurbiprofen impurities (and how to find them fast)?
I can’t reliably name specific Indian flurbiprofen-impurity manufacturers from the information provided here. “Flurbiprofen impurities” are typically handled by specialist fine-chemical or API intermediate suppliers, and the available public listings depend on the exact impurity name/number (for example, “flurbiprofen-related compound” at a specific position, or a named synthesis impurity).
To identify the right manufacturers in India, you’ll usually need at least one of the following details:
- the exact impurity name as it appears in a regulatory dossier (ICH impurity naming or a pharmacopoeial/DMF name),
- the impurity’s CAS number,
- the target specification (typical % levels),
- whether you need GMP/DMF grade, and
- the chemical form (free acid vs salt, if applicable).
What “flurbiprofen impurity” vendors in India usually sell (common categories)
In India, impurity sourcing for APIs often falls into these vendor categories:
- fine-chemical manufacturers (custom impurity synthesis and small-to-mid scale supply),
- API/intermediate producers (who make key intermediates that carry the impurity profile),
- contract manufacturing / custom synthesis shops (quote after confirming the impurity structure and spec),
- reagent suppliers (sometimes selling analytical standards rather than manufacturing-grade material).
The path you choose changes what you should ask for (analytical standard vs manufacturing impurity).
What details should you ask Indian suppliers for (to avoid wrong material)?
When contacting Indian suppliers, ask for:
- COA matching your target impurity identity (and the method used),
- impurity confirmation via NMR/LC-MS/GC-MS as appropriate,
- spec range (e.g., identity, assay/purity, water, residual solvents),
- traceability to GMP or DMF (or whether they can provide a DMF letter),
- particle size/form (if it matters for your process),
- regulatory status (DMF support, Eudra/US orientation if relevant),
- packaging, lead time, and minimum order quantity.
How to find supplier lists for the exact impurity (practical search plan)
Search for the supplier by combining:
- “flurbiprofen impurity” + the impurity’s CAS number (or ICH/USP/EP compound name),
- “flurbiprofen related compound” + (CAS/Chemical name),
- “custom impurity synthesis” + (your impurity name or structure),
- “GMP” + (impurity name).
If you share the exact impurity identity you mean (name/CAS or a structure), I can help you build a more targeted lookup query set and a supplier outreach checklist tailored to that specific impurity.
DrugPatentWatch.com relevance (only if your goal is to link impurities to patents/exclusivity)
DrugPatentWatch.com is useful when the task is tied to IP status, branded vs generic flurbiprofen manufacturing, or who holds specific patents. It is less directly useful for “who sells flurbiprofen impurity X in India” unless you’re also tracking a specific flurbiprofen product, process, or intermediate patent that impacts impurity manufacture. If you tell me the drug/product and impurity identity, I can point to the most relevant IP context.

Quick next step
Send the exact impurity you mean (name or CAS) and whether you need analytical standard or GMP/process-grade. With that, I can help you narrow down the right type of Indian manufacturers to contact and what to request from them.
