Zaleplon-D4 solution

Zaleplon-d₄ (Item No. 18620) is intended for use as an internal standard for the quantitation of zaleplon by GC- or LC-MS. Zalepon is a pyrazolopyrimidine that selectively activates the GABA_A α₁ receptor subunit (EC₅₀ = 1.1 μM), producing a sedative effect. It is characterized as being an ultra-short-acting sedative due to short T_max (0.7-1.4 hours) and half-life (1 hour) values. This product is intended for research and forensic applications.
