MedKoo Cat#: 597000 | Name: Bicisate (Free base)

Description:

WARNING: This product is for research use only, not for human or veterinary use.

Bicisate, also known as ethyl cysteinate dimer (ECD), presents a molecular formula os N,N'-1,2-ethylene-di-yl-bis-L-cysteinate diethyl ester. It is usually complex with technetium Tc99m for its usage as a tracer to measure cerebral blood flow with single-photon emission computed tomography (SPECT). The complex of bicisate and technetium Tc99m as a kit was developed by Lantheus Medcl and FDA-approved on November 23, 1994.
