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 .
Hantzsch ester refers to an organic compound with the formula HN(MeC=C(CO 2 Et)) 2 CH 2 where Me = methyl (CH 3) and Et = ethyl (C 2 H 5). It is a light yellow solid. The compound is a 1,4-dihydropyridine. It is named after Arthur Rudolf Hantzsch who described its synthesis in 1881.

Active esters are often used in peptide synthesis, e.g., N-hydroxysuccinimide, hydroxybenzotriazole. [1] Active esters of acrylic acid are precursors to polymers with reactive side chains. [4] The concept of active esters extends to esters of phosphoric and sulfuric acids. One such case is dimethylsulfate, a strong methylating agent.

Water purification combines a number of methods to produce potable or drinking water. Downstream processing refers to purification of chemicals, pharmaceuticals and food ingredients produced by fermentation or synthesized by plant and animal tissues, for example antibiotics, citric acid, vitamin E, and insulin.
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.
