| Abstract: | A reversed phase high performance liquid chromatography method for the determination of mercaptobenzothiazole disulfate(MBTS)purity was studied.A HP1100 liquid chromatography,e- quipped with a ZORBAX Stable Bond SB-C18 column and a UV detection(λ=280 nm)was used with 75% methyl alcohol/25% water as the mobile phase at flow rate 1.0 mL/min and column temperature (25±2)℃.The average recovery was 99.8%-100.2% with RSD 0.11% for MBTS. |
