Reagents are "substances or compounds that are added to a system in order to bring about a chemical reaction or are added to see if a reaction occurs." [1] Some reagents are just a single element. However, most processes require reagents made of chemical compounds. Some of the most common ones used widely for specific reactive functions are ...
The reagent was originally generated in situ by reducing iron pentacarbonyl with sodium amalgam. [5] Modern synthesis use sodium naphthalene or sodium benzophenone ketyls as the reducants: [1] [6] Fe(CO) 5 + 2 Na → Na 2 [Fe(CO) 4] + CO. When a deficiency of sodium is used, the reduction affords deep yellow octacarbonyl diferrate: [1]
In vivo dermal sensitization studies according to OECD 429 [3] confirmed DIC is a strong skin sensitizer, showing a response at 0.20 wt% in the Local Lymph Node Assay (LLNA) placing it in Globally Harmonized System of Classification and Labelling of Chemicals (GHS) Dermal Sensitization Category 1A.

Potassium hydroxide is an inorganic compound with the formula K OH, and is commonly called caustic potash.. Along with sodium hydroxide (NaOH), KOH is a prototypical strong base.
Anthrone is a tricyclic aromatic ketone.It is used for a common cellulose assay and in the colorimetric determination of carbohydrates. [1]Derivatives of anthrone are used in pharmacy as laxative.
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.
DPPA undergoes pseudohalogen replacement of the azido group by treatment with nucleophilic reagents, such as ammonia and various amines. [citation needed]This compound is used as a reagent for the synthesis of peptides by virtue of its reactions with carboxylic acids leading to either the urethane or the amide.
The length of the resulting polymer is dependent on the concentration of chain ending groups that are added to the reaction mixture. The rate of the reaction is determined by the transfer of reagents across the aqueous-organic phase boundary; therefore, the reaction is most efficient under turbulent conditions.
