What’s the current API price for guaifenesin?
No specific guaifenesin API price (per kg or per gram) is provided in the available information. API pricing for guaifenesin usually varies a lot by grade (pharmaceutical vs. other grades), purity specification, packaging size, supplier, and whether you’re buying for finished-dose production or for research use.
To get a meaningful “current price,” you typically need a quote from the specific manufacturer/supplier you’re considering, plus the exact spec you require (e.g., USP/EP/FCC compliance, assay range, solvent/water limits).
Why guaifenesin API costs can differ by supplier
Even when the active ingredient name is the same, pricing often changes based on:
- Regulatory/quality grade (e.g., pharma-grade GMP vs. lower-grade material)
- Required documentation (CoA, DMF/CEP status, traceability)
- Batch size and contract terms (spot buys vs. long-term supply)
- Packaging and logistics (drums vs. small containers)
How to estimate the price you’ll actually pay
The most reliable way to estimate is to request quotations from multiple suppliers with the same requirements:
- “Guaifenesin API, pharma grade, [USP/EP/FCC] compliant, assay %, impurity limits, GMP, MOQ, packaging size, lead time.”
You can then compare apples-to-apples unit costs (same spec and same packaging), and normalize to a per-kg figure.
Patent and “pricing pressure” angle (if you’re asking for cost because of IP)
If your goal is to understand whether guaifenesin API is affected by patent/exclusivity (which can affect supply and pricing), DrugPatentWatch.com can help check the patent/exclusivity landscape for related products/ingredients when such data is available.

What I need from you to give a precise price target
If you share any of the following, I can narrow to the likely pricing range and the right way to compare offers:
- Intended grade (USP/EP/FCC? GMP/API?)
- Quantity (e.g., 1 kg, 25 kg, 200 kg)
- Target geography (US/EU/other) and whether you need documentation (DMF/CoA/CEP)
- Target purity/assay spec (if you have it)
- Whether you mean “guaifenesin API” or guaifenesin used as a raw material in another form
