Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If nucleic acid derivative
Nucleic acids/salts (2934) have precedence; Chapter 29 numerical order rule applies after confirming no hetero-ring exclusion.
If primarily ether-alcohol function
Diols/ethers (2909) if oxygen functions dominate per heading 2911-2922 oxygen restriction notes.

Import Tips & Compliance
• Classify as oxidised amine derivative with NMR/CoA proof; avoid 2910 oxygen-function confusion
• Comply with OSHA carcinogen handling protocols
• Use refrigerated transport for thermal stability
