美国采购需求：化妆品原料、日用护理、精细化工、保健品、溶剂及助剂、有机原料

I'm looking to procure pharmaceutical grade methylene blue, specifically with a CAS number that you are likely familiar with. I'm interested in understanding your availability, pricing, and the minimum order quantities for this product. It's essential for us to source it from a reliable supplier who meets industry standards in quality. Additionally, could you provide details on your product specifications, including purity levels and any certifications? I'd also like to know the lead time for fulfillment and shipping options available. Please include any relevant information regarding payment terms and conditions. Looking forward to your prompt response!
