	Free Acid	Sodium Salt
Molecular Formula:	C21H14Br4O5S	C21H13Br4O5SNa
Molecular Weight:	698.0	720
CAS #	76-60-8	62625-32-5

Synonyms: 3',3'',5',5''-Tetrabromo-m-cresolsulfonephthalein; Bromcresol Green

Physical Description: Yellow to tan powder (free acid); Reddish-brown to Greenish-black crystalline powder (sodium salt)

Solubility: 
 

Free Acid: Soluble in water (6 mg/ml), ethanol (40 mg/ml) or methyl cellosolve (200 mg/ml)

Sodium Salt: Soluble in water (40 mg/ml) or ethanol (60 mg/ml).

Description: Tracking dye for DNA agarose electrophoresis. lmax = 617 (400) nm in water. Also used as a pH indicator (3.8 to 5.4 : yellow to blue-green).

Bromocresol green binds quantitatively with human albumin¹ forming an intense blue-green complex with an absorbance maximum at 628 nm. The intensity of the color produced is directly proportional to the albumin concentration in the sample.
