4-Pyrrolidinylpyridine is an organic compound with the formula (CH 2) 4 NC 5 H 4 N. The molecule consists of a pyrrodinyl group ((CH 2) 4 N-) attached via N to the 4-position of pyridine. It is a white solid. The compound has attracted interest because it (pK a = 9.58) is more basic than dimethylaminopyridine (pK a = 9.41). [1] It is a popular ...
Pyrrolidine, also known as tetrahydropyrrole, is an organic compound with the molecular formula (CH 2) 4 NH. It is a cyclic secondary amine , also classified as a saturated heterocycle . It is a colourless liquid that is miscible with water and most organic solvents.
Phenylboronic acid or benzeneboronic acid, abbreviated as PhB(OH) 2 where Ph is the phenyl group C 6 H 5 - and B(OH) 2 is a boronic acid containing a phenyl substituent and two hydroxyl groups attached to boron. Phenylboronic acid is a white powder and is commonly used in organic synthesis.
[2] [3] It is a "short-acting" or non-inactivating antagonist of the KOR (as opposed to irreversible antagonists like JDTic). [4] Although originally characterized as a KOR neutral antagonist however, subsequent research revealed in 2020 that PF-04455242 is actually only a moderately efficacious partial antagonist of the KOR ( I max ≈ 50%).

1-(2-Phenylethyl)pyrrolidine (PEP) is a chemical compound. It is an analogue of 2-phenylethylamine where the amine has been replaced by a pyrrolidine ring . The β- keto derivative is phenacylpyrrolidine and the α- methyl and β-keto (i.e., cathinone ) derivative is α-pyrrolidinopropiophenone (α-PPP).
4-Formylphenyl boronic acid crystallizes in colorless needles [2] or is obtained as an odorless, whitish powder, which dissolves little in cold but better in hot water. The compound is quite stable [4] and readily forms dimers and cyclic trimeric anhydrides, which complicate purification and tend to protodeboronize, a secondary reaction that occurs frequently in the Suzuki coupling, with ...
Dick Van Dyke still makes time for leg day. The actor celebrated his 99th birthday on Dec. 13, then appears to have hit the gym a few days later, according to a video shared on his Instagram page ...
In July 2016 α-PHiP was first identified as a designer drug [2] when it was reported to the EMCDDA by a forensic laboratory in Slovenia. [3] [4] It is a positional isomer of pyrovalerone, with the methyl group shifted from the 4-position of the aromatic ring to the 4-position of the acyl chain. Similarly to other cathinones, use of α-PiHP can ...
