Import Tips
• Require NMR spectrum verification of branched C8 structure to prevent misclassification as different chain length
• Store below 25°C; provide vapor pressure data (<0.1 mmHg) for VOC compliance declarations
• Avoid pitfall of C7/C9 mixture classification (2905.15/2905.22); assay must show >95% single isomer
