How should a new chemical which exists, in aqueous solution, in equilibrium with a “similar species” (also a new chemical) be reported on the PMN form?
A. If you have structurally-related substances in the situation described above, you will likely be given permission to submit a consolidated PMN notice (contact a Prenotice Communications Coordinator for a PC number.) Such a “one-pot” material can also be reported as a Class II chemical substance, if there is no intent to sell any of the components separately.
