Picrotoxin is an equimolar mixture of two compounds, picrotoxinin (C 15 H 16 O 6; CAS# 17617-45-7) and picrotin (C 15 H 18 O 7; CAS# 21416-53-5). [3] Of the two compounds, picrotin is less active. [4] Picrotoxin occurs naturally in the fruit of the Anamirta cocculus, a climbing plant from India and other parts of Southeast Asia. The plant is ...
This list is sorted by boiling point of gases in ascending order, but can be sorted on different values. "sub" and "triple" refer to the sublimation point and the triple point, which are given in the case of a substance that sublimes at 1 atm; "dec" refers to decomposition. "~" means approximately.
Pitolisant, sold under the brand name Wakix among others, is a medication used for the treatment of excessive daytime sleepiness in adults with narcolepsy. [3] It is an inverse agonist of the histamine H 3 receptor. [3]
Knowing the Mark–Houwink parameters and the molecular weight of one of the polymers allows one to find the molecular weight of the other polymer using a GPC. The GPC sorts the polymer chains by volume and as intrinsic viscosity is related to the volume of the polymer chain, the GPC data is the same for the two different polymers.
Chloropicrin's chemical formula is CCl 3 NO 2 and its molecular weight is 164.38 grams/mole. [9] Pure chloropicrin is a colorless liquid, with a boiling point of 112 °C. [ 9 ] Chloropicrin is sparingly soluble in water with solubility of 2 g/L at 25 °C. [ 9 ]
An overview of ranges of mass. To help compare different orders of magnitude, the following lists describe various mass levels between 10 −67 kg and 10 52 kg. The least massive thing listed here is a graviton, and the most massive thing is the observable universe.
All isomers share the molecular weight 123,11 g/mol and the chemical formula C 6 H 5 NO 2. See also. Pyridinedicarboxylic acid
Citrinin is a polyketide mycotoxin, which is a secondary metabolite of some fungi species. Its IUPAC name is (3R,4S)-4,6-dihydro-8-hydroxy-3,4,5-trimethyl-6-oxo-3H-2-benzopyran-7-carboxylic acid and the molecular formula is C 13 H 14 O 5. Citrinin has a molecular weight of 250.25 g/mol. It forms disordered yellow crystals which melt at 175 °C.
