Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If cyclic acetal derivatives rather than free aldehyde
Chapter notes exclude cyclic forms from aldehyde headings; acetals classify under separate heterocyclic provisions.
If pre-mixed as immunological product base
Immunological products containing organic compounds excluded from Chapter 29 per note 2(e).
If diagnostic reagent composite
Laboratory reagents containing glyoxal classify as composite diagnostic preparations.
