Import Tips
• Provide detailed chemical analysis (NMR, GC-MS) confirming sec-butyl chloride purity and isomer identity to avoid misclassification as n-butyl chloride
• Include Safety Data Sheet (SDS) and UN shipping papers for proper hazmat declaration as Class 3 flammable liquid
• Verify container compatibility with chlorinated solvents to prevent degradation during transport
