Substances used for the detection, identification, analysis, etc. of chemical, biological, or pathologic processes or conditions. Indicators are substances that change in physical appearance, e.g., color, at or approaching the endpoint of a chemical titration, e.g., on the passage between acidity and alkalinity. Reagents are substances used for the detection or determination of another substance by chemical or microscopical means, especially analysis. Types of reagents are precipitants, solvents, oxidizers, reducers, fluxes, and colorimetric reagents. (From Grant & Hackh's Chemical Dictionary, 5th ed, p301, p499)
使用Bromocresol Green is a pH sensitive indicator used in the growth medium for microorganisms and titrations. It is useful in various colorimetric detection studies and as an actively tracking dye for DNA agarose gel electrophoresis. It acts as an inhibitor of prostaglandin E2 transport protein. It is also used in TLC for visualizing compounds containing functional groups having pKa less than 5.
純化方法Crystallise the dye from glacial acetic acid or dissolve it in aqueous 5% NaHCO3 solution and precipitate it from the hot solution by dropwise addition of aqueous HCl. Repeat this until the UV/VIS-extinction did not increase 423nm. It is an indicator: at pH 3.81 at max (yellow) and pH 5.4 (blue-green). [Beilstein 19/3 V 460.]
