Stability

TETRAHYDRO-6-NITROQUINOXALINE typically appears as a pale yellow to light brown solid. A notable stability concern is its tendency to cause an orange-red discoloration upon contact with skin and to tint fur. While the free base is oil-soluble and can form aqueous suspensions (e.g., 1% with carboxymethylcellulose), its hydrochloride salt can be formulated into aqueous solutions up to 3%.

The Scientific Committee on Cosmetic Products and Non-Food Products (SCCNFP), a predecessor to the SCCS, concluded that TETRAHYDRO-6-NITROQUINOXALINE must be considered an in vitro mutagen. It is consequently listed as a prohibited substance in certain regulatory contexts and is not intended for use in consumer cosmetic products. Skin contact can lead to significant orange-red discoloration and is associated with high irritancy.
