Cat. No.: HY-W923198
CAS No.: 480439-15-4
Synonyms: Methacryloyloxy fluorescein
Fluorescein O-methacrylate (Methacryloyloxy fluorescein) is a pH-responsive fluorescent monomeric dye. Fluorescein O-methacrylate exhibits pH-responsive fluorescence properties: its fluorescence is activated under alkaline conditions and quenched under neutral or acidic conditions; reversible switching of fluorescence is achievable by adjusting the pH of the solution. Fluorescein O-methacrylate can be used as a monomer for the synthesis of amphiphilic fluorescein polymers. These polymers can self-assemble into stable polymer nanoparticles with enhanced aqueous-phase fluorescence, and also enable the conjugation of nanoparticles with amine-containing biomolecules to support sensitive optical detection of biomarkers (Ex/Em = 490/520 nm) .

Thymol blue
Thymol blue

Cat. No.: HY-D0219
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].

Cat. No.: HY-Y0286
CAS No.: 506-87-6
Synonyms: Hartshorn salt, 99%
Ammonium carbonate (Ammonium carbonate), 99% is a solid amino compound that functions as a buffer, pH regulator, pore-forming agent, and electrocatalytic oxidation substrate. Ammonium carbonate, 99% is a GRAS-grade direct food additive with no restricted daily intake specified by FAO/WHO, and it shows no acute skin toxicity, clinical signs of toxicity, or effects on body weight in rats. Ammonium carbonate, 99% undergoes electrocatalytic oxidation in alkaline solutions with a Pt/C catalyst (carbonate adsorption interferes with activity). Ammonium carbonate, 99% can serve as a fuel for low-temperature polymer fuel cells and anion exchange membrane fuel cells (with performance superior to pure ammonia), and can also form pores in the carrier-free Pt cathode catalyst layer after low-temperature decomposition, thereby enhancing catalyst activity under low-humidity conditions and the performance of proton exchange membrane fuel cells .

Sodium polyphosphate, crystal,+200 mesh, 96%
Sodium polyphosphate, crystal,+200 mesh, 96%
0 Images
Cat. No.: HY-W111692
CAS No.: 68915-31-1
Sodium polyphosphate, crystal,+200 mesh, 96% is an inorganic polyphosphate that also serves as a stabilizer, dispersant, chelating agent, and coacervate-forming agent. Sodium polyphosphate provides electrostatic stabilization for mineral and material suspensions, but its dispersing efficacy decreases under acidic pH, high temperature, high calcium concentration, or a combination of these conditions. Sodium polyphosphate can chelate alkaline earth metals, reduce solution pH, and alter the rate of pH decline at a divalent cation/phosphorus molar ratio of 0.18. Sodium polyphosphate forms coacervates with smaller divalent cations and precipitates with larger divalent cations, where the functional requirements of cations depend on polyphosphate concentration, average degree of polymerization, and cation type .

Cat. No.: HY-D0812
CAS No.: 125-31-5
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) .

Cat. No.: HY-D0228
CAS No.: 74-39-5
Synonyms: Azo Violet; Magneson I
4-(4-Nitrophenylazo)resorcinol (Azo Violet) is an azo purple dye used experimentally as a pH indicator, showing yellow when the pH value is lower than 11 and purple when the pH value is higher than 13. In slightly alkaline or alkaline environments, it also turns dark blue in the presence of magnesium salts. Azo Violet can also be used to test for the presence of ammonium ions. The color of the ammonium chloride or ammonium hydroxide solution will change depending on the concentration of azo violet used .
