Import Tips
• Provide reaction pathway documentation showing derivation from guaiacol base structure to support classification
• Test for glycerol content; excess may trigger reclassification as glycerol ether-alcohol under different provisions
• Include stability data confirming no decomposition products that alter chemical definition
