Chemical formula. C 4 H 4 Br N O 2: Molar mass: 177.985 g·mol −1 ... N-Bromosuccinimide or NBS is a chemical reagent used in radical substitution, ...
N-Iodosuccinimide (NIS) is a reagent used in organic chemistry for the iodination of alkenes and as a mild oxidant. [ 2 ] NIS is the iodine analog of N -chlorosuccinimide (NCS) and N -bromosuccinimide (NBS) which are used for similar applications.
Succinimide is an organic compound with the formula (CH 2) 2 (CO) 2 NH. This white solid is used in a variety of organic syntheses, as well as in some industrial silver plating processes. The compound is classified as a cyclic imide. It may be prepared by thermal decomposition of ammonium succinate. [4]
N-Hydroxysuccinimide (NHS) is an organic compound with the formula (CH 2 CO) 2 NOH. It is a white solid that is used as a reagent for preparing active esters in peptide synthesis. It can be synthesized by heating succinic anhydride with hydroxylamine or hydroxylamine hydrochloride .
N-Chlorosuccinimide (NCS) is the organic compound with the formula C 2 H 4 (CO) 2 NCl. This white solid is used for chlorinations. [2] It is also used as a mild oxidant. [3] NCS is related to succinimide, but with N-Cl in place of N-H. The N–Cl bond is highly reactive, and NCS functions as a source of "Cl +".
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. The low melting point of this material allows it to be melted for easy handling.
Tetraoctylammonium bromide (TOAB or TOABr) is a quaternary ammonium compound with the chemical formula: [CH 3 (CH 2) 7] 4 N Br. It is generally used as a phase transfer catalyst between an aqueous solution and an organic solution.
The bulk of the data deposited at the BMRB consists of over 11,900 entries containing 1 H, 13 C, 15 N and 31 P assigned chemical shifts and coupling constants of peptides, proteins and nucleic acids. [5] Other derived data like residual dipolar couplings (RDC), relaxation parameters, NOE values, order parameters and hydrogen exchange rates are ...
