This includes the utility of some dyestuff reagents namely bromothymol blue (BTB), bromophenol blue (BPN) and eriochrome blue black R (EBBR) for estimation of SILC in pure and pharmaceutical preparations. These reactions are applied for determination of SILC drug in its pharmaceutical preparaions UR - http://172.23.153.220/th.pdf ER -
