Abstract: Conditions for quantitative gas-chromatographic analysis of basic alkoxy carbanilates pentacaine and heptacaine after methylation with trimethylanilinium hydroxide were examined. The flash-heater derivatization reaction is reproducible and quantitative at 280°C. The reaction products, identified as N-methyl derivatives of the afore-mentioned carbanilates are thermally stable and their chromatographic response is linearly proportional to the increasing concentration.
