Bromkresolgrün Natriumsalz 0,04% in wässriger Lösung, Sigma-Aldrich®

Artikel-Nr: (318701-500ML)

Lieferant: SIGMA ALDRICH MICROSCOPY

Beschreibung: 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.

Bromkresolgrün Natriumsalz in ACS analysereinem Wasser ≥90% (durch HPLC), Sigma-Aldrich®

Lieferant: SIGMA ALDRICH MICROSCOPY

Beschreibung: 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.
