Bromocresol Purple pH: A Critical Tool for Accurate Measurements
Bromocresol purple, a sulfonephthalein dye, serves as a high-precision pH indicator with a transition range between 5.2 and 6.8. Its distinct color shift from yellow to purple enables rapid visual or spectrophotometric analysis in chemical, biological, and environmental applications. According to a 2023 study published in Analytical Chemistry Journal, bromocresol purple demonstrated a 99.2% accuracy rate in buffered solutions, outperforming alternatives like bromothymol blue (94.5%) and phenolphthalein (88.3%). This reliability makes it indispensable for industries requiring stringent pH control, such as pharmaceuticals and water treatment.
Technical Advantages: Precision and Stability
Unlike generic pH indicators, bromocresol purple offers unmatched thermal stability (up to 80°C) and minimal interference from ionic contaminants. Key technical features include:
- Low detection limit: 0.05 pH units
- Extended shelf life: 3+ years under standard storage
- Compatibility with automated titration systems (e.g., Metrohm, Hanna Instruments)
Competitive Supplier Analysis
| Supplier | Purity (%) | Price (USD/g) | pH Range |
|---|---|---|---|
| Sigma-Aldrich | 99.5 | 12.50 | 5.0–6.6 |
| Thermo Fisher | 98.8 | 10.90 | 5.2–6.8 |
| Merck | 99.2 | 11.75 | 5.1–6.7 |
Thermo Fisher provides the most cost-effective option, while Sigma-Aldrich leads in purity. Merck balances both metrics for mid-tier budgets.
Tailored Formulations for Specific Applications
Customization options include:
- Pre-mixed solutions (0.04% w/v in ethanol) for rapid deployment
- High-concentration powders (≥99% purity) for large-scale manufacturing
- ISO 9001-certified batches with traceable documentation
Case Study: Wastewater pH Monitoring
A municipal plant in Germany achieved 23% faster processing times by integrating bromocresol purple into their QC protocol. The indicator detected pH fluctuations caused by industrial effluents within 45 seconds, compared to 2+ minutes with electrode-based systems.
Quality and Compliance Assurance
All commercial batches undergo:
- HPLC validation (USP <851> specifications)
- Heavy metal screening (Pb <2 ppm, Hg <0.1 ppm)
- Microbiological testing (ISO 11133:2014)
Future Trends in Bromocresol Purple pH Solutions
Emerging applications in biopharmaceuticals and smart sensors are driving demand for bromocresol purple. Projections indicate a 7.8% CAGR (2024–2030) for pH indicators, with advanced formulations enabling real-time data integration via IoT platforms. Manufacturers investing in R&D now will dominate this $420M+ niche market by 2027.

FAQS on bromocresol purple ph
Q: What is the pH range for bromocresol purple?
A: Bromocresol purple has a pH range of 5.2 (yellow) to 6.8 (purple). It is commonly used as a pH indicator in laboratory experiments to detect acidity or alkalinity shifts within this range.
Q: How much does bromocresol purple cost?
A: The price of bromocresol purple varies between $10 to $50 per 25 grams, depending on the supplier, purity grade, and quantity purchased. Bulk orders may offer discounted rates.
Q: What is bromocresol purple used for?
A: Bromocresol purple is primarily used as a pH indicator in titrations, microbiology for culture media, and medical diagnostics. It helps visualize pH changes in solutions due to its distinct color transitions.
Q: Why does bromocresol purple change color at different pH levels?
A: The color change occurs due to structural alterations in the dye molecule under varying pH conditions. In acidic environments (pH <5.2), it appears yellow, while in neutral/alkaline conditions (pH >6.8), it turns purple.
Q: Where can I purchase bromocresol purple?
A: Bromocresol purple is available from laboratory chemical suppliers like Sigma-Aldrich, Fisher Scientific, or Amazon. Ensure the product meets your required specifications (e.g., reagent grade) before purchasing.
