acid yellow 1

Acid yellow 1 is a dye for amino acid and peptide precipitations.

Acid Yellow 199 is an azo dye that can be decolorized via a reduction reaction.

C.I. Acid Yellow 151 is an acidic yellow dye that can be adsorbed and removed by bentone.

C.I. Acid Yellow 172 is an acidic yellow dye that can be adsorbed and removed by bentone [a modified clay].

Metachrome yellow is a dye.

α-Naphtholbenzein, also known as p-Naphtolbenzein, is a dye that serves as a pH indicator, exhibiting a color change from yellow at a pH of 0-8.2 to turquoise at a pH of 10. It is commonly employed in the sequential injection analysis technique for acid-base titrations [1].

C12FDGlcU, a lipophilic analog of fluorescein di-β-D-glucuronic acid, is valuable for detecting β-glucuronidase (GUS) gene expression. This compound penetrates cells and is subsequently cleaved by β-glucuronidase, releasing a yellow-colored, green-fluorescent fluorescein (Abs Em of the reaction product: 495 518 nm) [1] [2].

Thymol Blue sodium, an acid-base indicator, changes from red to yellow at pH 1.2 to 2.8 and from yellow to blue at pH 8.0 to 9.6 [1]. Storage: protect from light.
