Bromophenol blue

C19H10Br4O5S, Indicator, CAS : 115-39-9

Bromophenol blue is a versatile dye commonly used in secondary school science studies. In biology, it is used as a tracking dye in agarose gel electrophoresis experiments to monitor the progress of DNA or protein separation. It helps students visualize the movement of molecules through the gel matrix. In chemistry, bromophenol blue is used as a pH indicator, changing color in response to changes in acidity or alkalinity of a solution. This property makes it useful in acid-base titrations and pH determination experiments. Its vibrant color and ease of use make bromophenol blue an excellent tool for teaching fundamental principles in biology and chemistry.

溴酚藍是一種多用途染料，常用於中學科學研究。 在生物學中，它被用作瓊脂糖凝膠電泳實驗中的示蹤染料，以監測DNA或蛋白質分離的進度。 它幫助學生可視化分子在凝膠基質中的運動。 在化學中，溴酚藍用作 pH 指示劑，根據溶液酸度或鹼度的變化而改變顏色。 此特性使其可用於酸鹼滴定和 pH 測定實驗。 其鮮豔的色彩和易用性使溴酚藍成為生物學和化學基本原理教學的絕佳工具。
