Meprobamate decomposes into NH4Cl, CO2, and a diol compound on heating in 20% HCl, and the NH3 evolved at pH above 11 can be determined using the NH3 selective electrode without separation from the decomposition solution. A linear calibration plot was obtained within the concentration range of 1×10-5-1×10-2M meprobamate. Volatile amines and the Hg ion, which forms a metal complex with NH3, are known to interfere with the electrode measurements.
