Import Tips & Compliance
• Use stainless steel drums with nitrogen blanketing; acetals are moisture-sensitive and hydrolyze during transit
• Pre-clear with FDA if ultimate use is pharmaceutical intermediate (even if not final drug)
• Document synthesis route to prove compliance with Chapter 29 purity requirements vs
• Chapter 38 preparations
