Thymol blue | Thymol blue is a reversible pH indicator that responds to the pH of the solution through structural changes of protonation and deprotonation. Thymol blue is red (HI- form) under acidic conditions and blue (I2- form) under alkaline conditions. Quantitative detection is achieved through the absorption peak shift (435 nm/596 nm) of the UV-visible spectrum. Thymol blue selectively responds to pH changes, changing from red to yellow at pH 1.2-2.8 and from yellow to blue at pH 8.0-9.6. Thymol blue can be fixed in a silica gel matrix through sol-gel technology to form a solid-state sensor for in-situ pH measurement in the marine environment and acid-base monitoring in the biomedical field. | |||||||||||||||||||||

Xylenol blue | 95.25% | Xylenol Blue is a sulfonephthalein dye. It exhibits observable color changes in response to variations in pH. Xylenol Blue undergoes two distinct color transitions across two specific pH ranges: an acidic range and an alkaline range. In a neutral solution, Xylenol Blue appears yellow (at pH 8); in a strongly acidic medium, its color shifts to red (at pH 2.8); and in an alkaline medium, the yellow hue transitions to blue (at pH 9.6). | ||||||||||||||||||||

Bromocresol green | 99.59% | Bromocresol green is a pH-sensitive triphenylmethane dye commonly used for the determination of protein and albumin in serum. Bromocresol green is a bio-based dye with a yellow-green to blue-green color. Bromocresol green turns yellow (λmax=435 nm, protonated form) when placed in acidic solution (e.g. pH=4.15), and turns blue in basic solution (λmax=615 nm, deprotonated form). Bromocresol green is widely used as a pH indicator in the field of biochemical analysis. In addition, Bromocresol green is also used to detect the concentration of molecules such as creatinine, and to judge the viability of cells. | ||||||||||||||||||||

Bromophenol blue indicator (3.0-4.6) | Bromophenol blue indicator (3.0-4.6) is a synthetic dye commonly used as an acid-base indicator with a transition range of pH 3.0-4.6. Bromophenol blue indicator (3.0-4.6) is water soluble and changes color from yellow to blue as the pH of the solution changes from acidic to basic. Its unique chemical properties make it an important ingredient in a variety of scientific applications, especially in biochemistry and molecular biology. In addition, it can be used as a stain in microbiology and histology. However, Bromophenol blue indicator (3.0-4.6) has potential irritating and staining properties. | |||||||||||||||||||||
