Acid Orange 10 G, also known widely as Orange G (CAS: 1936-15-8), is more than just a vibrant colorant; it possesses valuable indicator properties that are crucial in various chemical and biological analyses. Its function as a pH indicator hinges on its ability to undergo a distinct color change within a specific pH range, providing a visual cue for chemists and researchers.

The chemical structure of Acid Orange 10 G, an azo dye with sulfonate groups, contributes to its water solubility and its behavior in different pH environments. As a pH indicator, Acid Orange 10 G exhibits a transition range typically cited between pH 11.5 and 14.0. In this range, the dye transitions from a yellow hue at lower pH values (11.5) to a pink or reddish-pink color at higher pH values (14.0). This distinct visual shift allows for the approximate determination of alkalinity in solutions, making it useful in titrations and other analytical procedures where monitoring pH changes is essential.

While its primary industrial and biological staining applications are well-documented, its utility as a pH indicator adds another layer of value. Researchers in laboratories often need to buy and utilize chemicals that serve multiple purposes to streamline their processes and manage inventory effectively. Acid Orange 10 G, sourced from reliable manufacturers, can fulfill both its role as a stain and as a basic pH indicator.

For those looking to purchase Acid Orange 10 G for these dual purposes, focusing on suppliers who guarantee the dye's purity and indicator capabilities is important. Manufacturers in China, like NINGBO INNO PHARMCHEM CO.,LTD., can provide high-quality Acid Orange 10 G that is suitable for precise laboratory work. Whether you are performing complex histological staining or requiring a visual indicator for alkaline solutions, understanding the specific pH transition range of Acid Orange 10 G ensures its effective application in your work.
