Finerenone impurity manufacturers in india?

I’m not aware of any public list of “finerenone impurity manufacturers in India.” Impurities (especially for an API like finerenone) are typically handled under confidential licenses between the sponsor (e.g., Bayer or the current API licensor) and licensed manufacturers or impurity reference-standard suppliers. Regulators don’t publish open directories of impurity manufacturers.

If you have a legitimate, compliant need (e.g., analytical method development, reference standards), here are practical paths:

- For impurity reference standards (impurities used as analytical references):
- Check major pharmaceutical reference standard suppliers (often globally, but they also have Indian distributors). Examples include Merck/Sigma-Aldrich, Thermo Fisher, and LGC Standards. Indian distributors or local vendors like Qualikems, SRL, and similar chemical suppliers sometimes carry PRS for common impurities or can source them on request.
- Contact your QA/Regulatory team to ensure you obtain certified reference standards with proper documentation (certificate of analysis, GMP compliance, traceability to ICH requirements).

- For regulatory and impurity profile information:
- ICH guidelines: Q3A (impurities in drug substances) and Q3B (impurities in drug products) for definitions, qualification, and reporting of impurities.
- The official impurity profile data for finerenone would be in its regulatory filings (NDA/MAA) or in the API’s technical dossier provided to the sponsor. You’d typically obtain this through the sponsor or regulatory channels, not from a public vendor list.

- For custom synthesis of impurities (if you need an impurity not available as a standard):
- Approach licensed Indian CMOs/CDMOs that offer GMP synthesis of impurities under a confidential agreement. Ensure they have the necessary regulatory licenses (GMP, DCGI/CDSCO-compliant) and that you have proper non-disclosure and QA documentation.

- If you’re trying to identify actual Indian manufacturers for finerenone API or related impurities:
- You’d typically search regulatory databases or contact the NDA/MAA holder (currently the sponsor of finerenone) or consult with a licensed API directory in India. Publicly listing who makes specific impurities is not common.

If you can clarify exactly what you need (e.g., “I need a vendor to supply finerenone impurity reference standards for method validation” or “I need names of Indian API manufacturers with finerenone production for regulatory purposes”), I can tailor steps, email templates, and regulatory checks to your use case.
