CAS 2214-72-4: N,N'-bis-(2-Chloroethyl)urea

CARMUSTINE IMPURITY A CRS

N,N'-Bis-(2-chloroethyl)-urea is a molecule that inhibits the activity of the enzyme carmustine. It binds to the active site of ns3 protease and prevents it from cleaving other proteins. N,N'-Bis-(2-chloroethyl)-urea has been shown to have synergic effects with other chemotherapeutic agents. Its pharmacokinetic properties have been studied in detail and found to be stable in blood plasma, urine samples, and rat liver microsomes. N,N'-Bis-(2-chloroethyl)-urea is an analytical method for detecting dinucleotide phosphate in biological samples.

Stability Hygroscopic, Unstable in Solution Applications 1,3-Bis(2-chloroethyl)urea is an impurity in the synthesis of Carmustine (C183875), an alkylating and carbamoylating nitrosourea compound. It interacts with DNA, RNA and proteins causing DNA interstrand cross linking which is cytotoxic and leads to apoptotic cell death. Not a dangerous good if item is equal to or less than 1g/ml and there is less than 100g/ml in the package References Stahl, et al.: Chem. Res. Toxicol., 5, 106 (1992), Kokkinakis, D.M., et al.: Clin.
