Methodology:
The titration method was used: 25 mL of [1] and an amount of (2) exceeding the solubility were placed into 50 mL volumetric flasks. The flasks were closed by ground stoppers and were stored at the required temperature in a thermostat for 45 hours, with intensive stirring every several hours. After this, 5 mL samples of the saturated solution were taken by pipette, diluted to 25 mL with nitromethane and titrated against 0.07 N tetrabutylammonium hydroxide solution by using bromothymol blue indicator.
Sample Information:

- Source not specified; purity not specified; purified by crystallization from water.
Measurement Errors:
Ambient temperature: Not reported.
Mass concentration (m/v) (1): Not reported.
