Import Tips
• Provide structural formula and NMR spectra if requested to distinguish from other indole isomers
• Classify based on principal characteristic group; methyl substitution doesn't change indole heading
• Watch for common pitfall of classifying as 'other heterocyclic' - specific indole derivatives stay here
