Bromocresol green sodium salt 0,04% in aqueous solution, Sigma-Aldrich®

Catalog Number: (318701-500ML)
Supplier: SIGMA ALDRICH MICROSCOPY
Description: Bromocresol green is a sulfonephthalein dye. It is mainly used for measuring serum albumin. In acidic conditions, bromocresol green interacts with albumin, thereby resulting in an increase in absorbance at 630 nm. The change in absorbance is linked with the concentration of albumin. Bromocresol Green is also a pH indicator, changing from yellow (pH 3.8) to blue color (5.4). It is widely used as a colloidal pigment.

Bromocresol green sodium salt in ACS Reagent grade water ≥90% (by HPLC), Sigma-Aldrich®

Supplier: SIGMA ALDRICH MICROSCOPY
Description: Bromocresol Green (BCG), also known as bromcresol green, is a synthetic, anionic, triphenylmethane dye belonging to the phthalein and sulphonphthalein dyes group. It is commonly used as a pH indicator as it changes colour from yellow to blue-green at pH 3,8 to 5,4. The monosodium salt of bromocresol green is highly ionisable in water. The dye at a higher pH level produces a large and weakly lipophilic dianion.

o-Tolidine ≥95%

Supplier: SIGMA ALDRICH MICROSCOPY
Description: o-Tolidine is a diacidic dye which is sparingly soluble in water and easily soluble in ether and alcohol. On exposure to chlorine or bromine vapors, it forms an intense blue color. This forms the basis for detection of chlorine, nitrates and hydrogen peroxide in air or water. It turns yellow on reacting with free chlorine. o-Tolidine easily forms acid salts.

Xylenol orange tetrasodium salt in ACS Reagent grade water, Sigma-Aldrich®

Supplier: SIGMA ALDRICH MICROSCOPY
Description: Xylenol orange tetrasodium salt is a fluorochrome acid dye with complexing and chelating properties that make it useful as an indicator in the spectrophotometric detection and assay of metal ions such as calcium, cadmium, bismuth, zinc, lead, and mercury. Its tetrasodium salt especially is used as an indicator in metal titrations. It changes color from yellow to red between pH 6.4 to 10.4. It has six potentially anionic substituents, one being sulfonate, and is anionic under staining conditions and during most laboratory applications.
