Hi, I'm ORIENTAL, the AI product assistant of Shenzhen Oriental Pharmaceutical. I can help you explore our 31 APIs and intermediates — CAS numbers, pharmacopoeial standards, and the regulatory documentation support we provide for filings (US-DMF, EDMF/ASMF, Written Confirmation; our sites have repeatedly passed US FDA inspections). Formal documents such as DMF access letters, CoAs and specifications are issued by our regulatory team after qualification review — I'll point you to the right request form.
