Chromogenic thiol indicators based on an isobenzothiazolone ring system |
abstract |
Newly synthesized chromogenic thiol-indicating benzoisothiazolone derivatives having the structure: ##STR1## where R 1 , R 2 and R 3 are as defined in the specification, are useful in the detection of thiols, particularly in an aqueous system. This process comprises contacting the aqueous system with a chromogenic thiol-indicating benzoisothiazolone derivative as described herein. Chromophoric changes due to thiol-mediated reduction of the benzothiazolone derivative then occur. Such changes can be in a solution or on an indicator surface in contact or having been in contact with the aqueous system. The chromophoric changes, due to a bathochromic shift in characteristic light absorption upon reduction of the benzoisothiazolone derivative, are proportional to the amount or rate of appearance of thiols in the aqueous system. |
