Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If used primarily as a base rather than oxygen-function compound
Amine-function emphasis in end-use might prioritize 2921 over 2922 per numerical order rule.
If cyclized or containing excluded ring structures per note to 2932-2934
Heterocyclic derivatives exclude from acyclic oxygen-amino compounds in 2922.

Import Tips & Compliance
• Obtain DMF or equivalent for pharma imports; cross-check with FDA chemical database
• Ensure <10 ppm heavy metals per USP standards to avoid Chapter 28 inorganic classification
