BRL-41992 is a selective α₂B-adrenergic receptor antagonist. BRL-41992 exhibits 94-fold higher selectivity for the α₂B-receptor than for the α₂A-receptor with Kᵢ values in neonatal rat lung tissue (expressing the α₂B-receptor) and in human platelet membranes (expressing the α₂A-receptor) of 1.1 and 103.3 nM. BRL-41992 can be used to verify the functional differences of α₂ receptor subtypes.

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.
