Although DCM is a common solvent in organic chemistry laboratories and is commonly assumed to be inert, it does react with some amines and triazoles. [21] Tertiary amines can react with DCM to form quaternary chloromethyl chloride salts via the Menshutkin reaction. [22]
N,N′-Dicyclohexylcarbodiimide (DCC or DCCD) [1] is an organic compound with the chemical formula (C 6 H 11 N) 2 C. It is a waxy white solid with a sweet odor. Its primary use is to couple amino acids during artificial peptide synthesis.
MDC-600 and MDC-1200, an AFSK mobile data format used in Motorola two-way radios; Message digest code, cryptographic hash value; Metadata controller, which manages file locking, space allocation and data access authorization in a storage area network (SAN)
Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
Additionally, EDC can also be used to activate phosphate groups in order to form phosphomonoesters and phosphodiesters. Common uses for this carbodiimide include peptide synthesis, protein crosslinking to nucleic acids, but also in the preparation of immunoconjugates.
Methanesulfonyl chloride is mainly used to give methanesulfonates by its reaction with alcohols in the presence of a non-nucleophilic base. [8] In contrast to the formation of toluenesulfonates from alcohols and p-toluenesulfonyl chloride in the presence of pyridine, the formation of methanesulfonates is believed to proceed via a mechanism wherein methanesulfonyl chloride first undergoes an ...
MDC and other non-N-substituted cathinones such as cathinone itself are chemically unstable due rapidly forming biologically inactive dimers and this has limited their prevalence. [ 1 ] Monoamine release of methylenedioxycathinone and related agents ( EC 50 Tooltip Half maximal effective concentration , nM)
DEAD was used in the original 1967 article by Oyo Mitsunobu, [14] and his 1981 review on the use of diethyl azodicarboxylate is a top-cited chemistry article. [ 15 ] [ 16 ] The Mitsunobu reaction has several applications in the synthesis of natural products and pharmaceuticals.
