Specs & features.
Bromocresol Purple (BCP) is a versatile sulfonephthalein dye used as a pH indicator and analytical reagent. In veterinary medicine and science, it primarily serves as an active component in spectrophotometric albumin tests, microbiological culture media, and diagnostic assays to identify metabolic byproducts or specific pathogens.
No specifications have been listed.
- Visual pH Transition: BCP operates in a pH range of 5.2 to 6.8. It transitions from yellow at acidic pH (5.2 or lower) to a distinct purple/violet color at neutral to alkaline pH (6.8 or higher).
- Protein Binding: The dye strongly binds to serum albumin, allowing for rapid and precise quantification.
- Stability: When incorporated into agar media, it withstands standard sterilization processes such as autoclaving.
