• Provide clinical indication documentation as niche therapeutic use may trigger additional FDA scrutiny
• Ensure proper polymorphic form certification as sulfapyridine exhibits multiple crystal forms affecting bioavailability
• Declare exact CAS number (144-83-2) on commercial invoice for accurate HTS verification
