Benzamidine hydrochloride
Benzamidine hydrochloride (CAS: 1670-14-0) is a chemical compound with the formula C6H5C(=NH)NH2 · HCl and a molecular weight of 156.61 g/mol. It is primarily recognised as a potent inhibitor of serine proteases such as trypsin and thrombin. Its specific inhibitory action makes it a valuable tool in biochemical research and for stabilising protein samples during purification processes, preventing enzymatic degradation.

Protease Inhibition
Acts as a reversible inhibitor for serine proteases, notably trypsin and thrombin. This property is crucial for preventing protein degradation during biochemical isolation and purification procedures.
Biochemical Research
Utilised as a standard reagent in molecular biology and biochemistry laboratories to study enzyme kinetics and protein function. It helps in understanding the mechanisms of protease activity.
Protein Sample Stabilisation
Incorporated into buffer solutions to maintain the integrity of protein samples. By inhibiting endogenous proteases, it ensures accurate downstream analysis of protein structure and function.
