Dibenzothiophene (DBT, diphenylene sulfide) is the organosulfur compound consisting of two benzene rings fused to a central thiophene ring. It has the chemical formula C 12 H 8 S. It is a colourless solid that is chemically somewhat similar to anthracene .
Tincture of cannabis, sometimes known as green dragon, is an alcoholic cannabis concentrate.The solubility of THC in ethanol is greater than 1 g/mL. [1]According to the European Medicines Agency (EMA) cannabis tinctures (tincturea) are a type of liquid cannabis extract obtained using ethanol, water, glycerol, propylene glycol and fatty oils as extraction solvents, depending on the type of ...
Some alkaloids are more stable as ionic salts than as free base. The salts usually exhibit greater water solubility. Common counterions include chloride, bromide, sulfate, phosphate, nitrate, acetate, oxalate, citrate, and tartrate. Ammonium salts formed from the acid–base reaction with hydrochloric acid are known as hydrochlorides.
Dibenzofuran is a relatively non-toxic compound as evidenced by rats being unaffected after a 200-day diet consisting of 0.025 – 0.4% of DBF. [1] The polychlorinated dibenzofurans are however among the potentially toxic dioxins and dioxin-like compounds.
It is the principal psychoactive constituent of cannabis and one of at least 113 total cannabinoids identified on the plant. Although the chemical formula for THC (C 21 H 30 O 2 ) describes multiple isomers , [ 10 ] the term THC usually refers to the delta-9-THC isomer with chemical name (−)- trans -Δ 9 -tetrahydrocannabinol .
Dibenz(a,h)anthracene is a polycyclic aromatic hydrocarbon with five benzene rings. It has low water solubility and low volatility and therefore occurs predominantly in solid form, white to light yellow crystalline, bound to particulates in polluted air, soil, or sediment. [2]
Benzophenone has been found in some fungi, fruits and plants, including grapes. [4] It is a white solid with a low melting point and rose-like odor [ 5 ] that is soluble in organic solvents. Benzophenone is the simplest diaromatic ketone .
Piperonal can be prepared by the oxidative cleavage of isosafrole or by using a multistep sequence from catechol or 1,2-methylenedioxybenzene.Synthesis from the latter chemical is accomplished through a condensation reaction with glyoxylic acid followed by cleaving the resulting α-hydroxy acid with an oxidizing agent.
