CAS No.: 76-61-9
Synonyms: Thymolsulphonephthalein
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 (I 2- 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[1][2].

DC271 is a RAR agonist and synthetic retinoid that binds to the retinoid-binding site of cellular retinoic acid-binding protein II (CRBP-II). DC271 exhibits solvatochromic fluorescence properties: it produces intense blue-shifted emission in nonpolar environments and weak red-shifted emission in polar environments, and its severe fluorescence quenching in aqueous solutions can be reversed by embedding in the hydrophobic retinoid-binding protein pocket. DC271 enables direct detection of the binding between unlabeled compounds and related retinoid-binding proteins via fluorescence competition assays (Ex/Em = 355 nm/460 nm) .

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) .
