Benzethonium Chloride, also known as Hyamine, is synthetic quaternary ammonium salt that has surfactant, antiseptic, and anti-infective properties. Benzethonium Chloride is commonly used as a topical antimicrobial agent. Benzethonium chloride exhibited concentration-dependent inhibitions of HERG channel currents with IC(50) values of 4nM and 17nM, respectively, which were also voltage-dependent and use-dependent. Benzethonium Chloride shifted the channel activation I-V curves in a hyperpolarized direction for 10-15mV and accelerated channel activation and inactivation processes by 2-fold.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
