Import Tips
• Confirm anilino-naphthyl structure via NMR spectra for CBP lab verification if challenged
• Declare salts separately if mixed; note 2(C)(2) requires classification by the later-occurring component
• Ensure no coordination with metals, as note 2(C)(3) affects classification for complexes
