2-NITRO-5-THIOCYANATOBENZOIC ACID Chemical Properties,Usage,Production

Chemical Properties

yellow fine crystalline powder

Uses

2-Nitro-5-thiocyanatobenzoic acid (NTCB) is a highly reactive reagent that transfers its cyano group rapidly to a nucleophilic thiolate. 2-Nitro-5-thiocyanatobenzoic acid has been proposed as a reagent for converting thiol groups in proteins into their S-cyano derivatives[1][2].

Biological Activity

2-nitro-5-thiocyanatobenzoic acid (NTCB) is commonly used to cyanylate and cleave proteins at cysteine residues.
