| Bromocresol green | 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 [1] [2] [3] [4]. Uses: Scientific research. Group: Biochemical assay reagents. CAS No. 76-60-8. Pack Sizes: 10 mM * 1 mL; 25 g; 50 g; 100 g. Product ID: HY-W040144. |  |
| Bromothymol Blue, Sodium Salt, ACS (Dibromothymolsulfone phthalein, BTB) | Bromothymol blue (alt: dibromothymolsulfoneph thalein, bromthymol blue, BTB) is a chemical indicator for weak acids and bases. The bromothymol blue acts as a weak acid in solution and therefore can be in acid or base forms which appear yellow and blue respectively. It is green in neutral solution. Bromothymol blue is typically sold in solid form as the sodium salt of the acid indicator. It also finds occasional use in the laboratory as a biological slide stain. At this point it is already blue, and a drop or two is used on a water slide. The coverslip is placed ontop of the water droplet and the specimen in it, with the blue coloring mixed in. It is sometimes used to define cell walls or nuclei under the microscope.Bromothymol blue is mostly used in measuring substances that would have relatively low acidic or basic levels (near a neutral pH). It's often used in pools, fish tanks, or measuring the presence of carbonic acid in a liquid. Group: Biochemicals. Alternative Names: 3', 3''-Dibromothymolsulfoneph thalein sodium salt; BTB.

| Potassium iodide | Potassium iodide is an inorganic compound with the chemical formula KI. This white salt is the most commercially significant iodide compound, with approximately 37,000 tons produced in 1985. It is less hygroscopic (absorbs water less readily) than sodium iodide, making it easier to work with. Potassium iodide occurs naturally in kelp. Kelps iodide content can range from 89 μg/g to 8165μg/g.Aged and impure samples are yellow because of the slow oxidation of the salt to potassium carbonate and elemental iodine.Potassium iodide is medicinally used for thyroid blockade, thyroid storm and also as an expectorant. It is on the WHO Model List of Essential Medicines, the most important medications needed in a basic health system. Group: Electrolytes. Alternative Names: Potassium monoiodide. CAS No. 7681-11-0.
