说明

溴百里酚蓝是弱酸和碱的pH指示剂。在中性溶液中，它呈现蓝绿色。在pH高于7.6时呈蓝色，在pH低于6.0时呈黄色。
溴百里酚蓝（BTB）是阴离子染料。它可以被质子化或去质子化以产生黄色或蓝色。BTB有助于制备离子对复合物，用于借助萃取分光光度法鉴定几种药物化合物。

一般描述

Bromothymol blue is a pH indicator for weak acids and bases. In neutral solution, it appears bluish-green. At pH above 7.6 it appears blue, and at pH below 6.0 it appears yellow.
Bromothymol blue (BTB) is an anionic dye. It can be protonated or deprotonated to generate yellow or blue. BTB helps to make ion-pair complex, that is used to identify several pharmaceutical compounds with the help of extractive spectrophotometric methods.[1]
