Hello. delta-9 carboxy thc is the primary pharmacologically active component of marijuana.It is formed by oxidation of 11 hydroxy delta 9 thc in liver and is detectable in plasma and urine for a much longer time than delta 9THC and is therefore the metabolite tested for finding previous marijuana use.ased on these results it would seem that you son had used marijuana shortly before the test since the THC level is still elevated AND the relatively high level of carboxy THC suggest chronic use. Here is some information on the interpretation of levels and the impairment of driving.
Tetrahydrofuran (THF) is an organic compound with the formula (CH 2) 4 O. The compound is classified as heterocyclic compound, specifically a cyclic ether. It is a colorless, water-miscible organic liquid with low viscosity.It is mainly used as a precursor to polymers.n the laboratory, THF is a popular solvent when its water miscibility is not an issue. It is more basic than diethyl ether and forms stronger complexes with Li + , Mg 2+ , and boranes. It is a popular solvent for hydroboration reactions and for organometallic compounds such as organolithium and Grignard reagents.
