Import Tips
• Include NMR or HPLC purity certificates (>99%) to confirm heterocyclic lactam identity and avoid amide reclassification
• Comply with TSCA inventory requirements; provide end-use declaration to prevent diversion to restricted solvent applications
• Watch for misclassification as N-methylpyrrolidone (different HTS 2933.79.29); verify methyl substitution absent
