It was found that an aminovinyl compound, KANKOH-SO No. 301 or KANKOH-SO No. 401 reacted to form an insoluble complex with tetraphenylboron. The assay by conductometric titration method for KANKOH-SO No. 301 and KANKOH-SO No. 401 was developed, since complex formation was shown to cause changes in conductivity.When the aminovinyl compounds were titrated with tetraphenylboron in 40% methanol solution, a good correlation was obtained between the amount of compounds and change in conductivity in terms of linearity.It was concluded that this is a simple and prompt method of assay for KANKOH-SO No. 301 and KANKOH-SO No. 401.
