How useful is thymol blue (acid) as an indicator?

[The pH range of thymol blue (acid) is 1.2-2.8.](https://www.vanderbilt.edu/AnS/Chemistry/courses/chem104/experiment5/titration4.htm). This pH range seems pretty useless. Generally, the sudden change in pH for SA-SB titration occurs in the range of 4-10; the sudden change in pH for SA-WB titration occurs in the range of 4-7, and the sudden change in pH for WA-SB titration occurs in the range of 8-10.


None of the ranges overlap with the pH range of thymol blue (acid), which is 1.2-2.8. When I found this indicator listed in my book, naturally I thought why this indicator is even listed here as its pH range seems pretty useless.


Are there any acid-base titrations/reactions where thymol blue (acid) is used as an indicator?
