I am a medical doctor currently pursuing an MSc in Dermatology. I am conducting research for my master’s thesis on a topical formulation for the treatment of melasma. I am looking for Olopatadine Hydrochloride Active Pharmaceutical Ingredient (API) to formulate a research cream for laboratory and clinical research purposes.

The API should be of high pharmaceutical purity and suitable for pharmaceutical compounding/formulation. Please provide the following information:

* Available purity/grade (preferably pharmaceutical or USP/EP grade, if available)
* Certificate of Analysis (CoA)
* Product specifications
* Available package sizes
* Price quotation
* Shipping to Thailand
* Estimated delivery time

Thank you. I look forward to your quotation.
