Trimethylbenzene, 1,2,3- cleanup levels by state
- CAS 526-73-8
- 2 states
CAS 526-73-8 is in the cleanup-level tables of 2 states in this handbook: Florida (Trimethylbenzene, 1,2,3-) and Texas (Trimethylbenzene, 1,2,3-). Each state's numbers are below as its agency prints them. The states run different programs and do not define their values the same way, so a number from one is not the same measure as a number from another. A state that lists the substance under another CAS number, or without one, is not shown here.
