N-BROMOACETAMIDE

The Uses of N-BROMOACETAMIDE

N-bromoacetamide annihilates the rapid inactivation of membrane sodium-ion channels. Also functions in the kinetics of cardiac sodium ion channels.

The Uses of N-BROMOACETAMIDE

Abolishes the rapid inactivation of membrane sodium- and potassium-ion channels.

General Description

White powder.

Air & Water Reactions

Soluble in water.

Reactivity Profile

N-BROMOACETAMIDE is sensitive to light, moisture, and heat. . N-BROMOACETAMIDE decomposes rapidly at elevated temperatures, in the presence of moisture and light.

Fire Hazard

Flash point data are not available for N-BROMOACETAMIDE, but N-BROMOACETAMIDE is probably combustible.

Purification Methods

A possible contaminant is CH3CONBr2. Recrystallise it from CHCl3/hexane (1:1, seed if necessary) or water and dry over CaCl2. It is a brominating agent. [Oliveto & Gerold Org Synth Coll Vol IV 104 1963.] Alternatively, dissolve it in the minimum volume of warm H2O (60o), then cool in an ice bath, collect the crystals and dry them in an anhydrous atmosphere, dissolve in Et2O, chill and evaporate till crystallisation. Dry the crystals in vacuo at 25o, then at 45o (m 108o). Crystallise from CHCl3 (m 103o). Estimate the available Br iodometrically [Buckles et al. J Org Chem 23 483 1958]. [Beilstein 2 H 181, 2 I 82, 2 II 180, 2 III 406, 2 IV 417.]
