Ferrozine, chemically 3-(2-Pyridyl)-5,6-bis(4-phenylsulfonic acid)-1,2,4-triazine disodium salt, is a water-soluble solid. It is complexometric reagent for detection and estimation of iron.
Sodium thiosulfate is an inorganic compound, typically available as the white or colorless pentahydrate. The solid is an efflorescent (loses water readily) crystalline substance that dissolves well in water.
Sodium tert-butoxide is a stronger base (than primary and secondary alcoholates) and a non-nucleophilic base. It is flammable and moisture sensitive.
Permethrin is an insecticide in the pyrethroid family. Pyrethroids are synthetic chemicals that act like natural extracts from the chrysanthemum flower.
Succinonitrile is a colorless, low melting solid belonging to dinitrile category of organic compounds. The presence of two cyano groups renders the molecule reactive and thus it undergoes various reactions.
Piperazine is a cyclic ethylene amine with two secondary amine groups. Piperazine is supplied as (anhydrous) Piperazine 99%.
n-Butyllithium is a colorless, organic liquid. It belongs to the organometallic category of compounds. It participates in a variety of chemical reactions and acts diversly as lithiation, alkylation, metalating, and deprotonation agent.
