m-Cresol Purple is a pH indicator dye used primarily in spectrophotometric pH measurement. It operates in the pH ranges 1.2 – 2.8 (red to yellow) and 7.4 – 9.0 (yellow to violet). Further, m-Cresol Purple is employed to stain epithelial cells and proteins. A chemical structure of a molecule includes the arrangement of atoms and the chemical bonds that hold the atoms together. Experimentally determined physical and chemical characteristics of purified meta-Cresol Purple (mCP) pH indicator dye suitable for pH measurements in seawater and conservative seawater-derived brines at salinities (S) between 35 and 100 and temperatures (T) between their freezing point and 298.15 K (25 °C). Within this temperature and salinity range, using purified mCP and a novel thermostated spectrophotometric device, the pH on the total scale (pHT) can be calculated.m-Cresol Purple is a recommended indicator for open-ocean pH measurements. The compound is used in many colorimetric sensor studies.

Bromocresol Purple Sodium Salt (Water-Soluble) is a high-purity pH indicator dye widely used in laboratory, diagnostic, and biochemical applications. It appears as a reddish-brown to purple powder and is readily soluble in water, forming a solution that transitions from yellow at acidic pH (~5.2) to purple at alkaline pH (~6.8). With a molecular formula of C₂₁H₁₅Br₂NaO₅S and a molecular weight of approximately 562.2 g/mol, this compound is ideal for use in titrations, buffer system analysis, and other analytical procedures where precise pH indication is required. The product is available in various pack sizes and is typically supplied with ≥90% dye content, meeting reagent-grade specifications. It should be stored in a cool, dry place in tightly sealed containers to maintain stability and shelf life. Standard safety precautions apply, as the substance may cause irritation upon contact or inhalation.
