Selecting the appropriate pH indicator is critical for the success of many chemical analyses, particularly acid-base titrations. Methyl Red Sodium Salt (CAS 845-10-3) stands out due to its specific pH transition range of 4.4 (red) to 6.2 (yellow). This range makes it particularly well-suited for titrating strong acids with weak bases, or weak acids with strong bases where the expected pH at the equivalence point falls within this interval.

Compared to other common indicators, Methyl Red offers a sharper color change in its specific pH zone. For instance, indicators like Bromothymol Blue have a wider range (6.0-7.6), making them suitable for titrations of strong acids with strong bases, or weak acids with weak bases where the pH change is less pronounced. Phenolphthalein, with its range of 8.2-10.0, is ideal for titrating weak acids with strong bases.
