Phenolphthalein Powder – ACS Grade – High-Purity pH Indicator

Description

Phenolphthalein Powder (ACS Grade) is a high-purity chemical compound certified to meet American Chemical Society (ACS) standards, ensuring the highest quality for analytical and laboratory applications. Renowned for its sharp color change, it is widely used as a pH indicator in acid-base titrations and other analytical processes. Its precision and reliability make it indispensable in research, education, and industrial settings.

Applications of Phenolphthalein Powder – ACS Grade

Acid-Base Titrations

• Key pH Indicator: Used extensively in laboratories to determine the endpoint of acid-base titrations, transitioning from colorless in acidic solutions to pink/magenta in basic solutions (pH 8.2–10.0).
• Ideal for research and educational experiments requiring precise pH measurements.

Analytical Chemistry

• Quantitative Analysis: Employed in analytical methods to assess acidity, alkalinity, and neutralization processes in various chemical samples.
• Frequently used in quality control laboratories to monitor pH levels in manufacturing processes.

Environmental Testing

• Water Quality Testing: Assesses alkalinity in water samples for environmental monitoring.
• Soil pH Analysis: Determines the pH of soil for agricultural and environmental studies, helping to improve soil management practices.

Educational Use

• Chemistry Demonstrations: Used in academic settings to teach students about pH, acid-base reactions, and titration techniques.
• Provides clear, visual results that are easy to interpret for learners.

Industrial Applications

• Chemical Manufacturing: Used in processes requiring precise pH monitoring and control.
• Product Development: Supports formulation and quality assurance in industries such as pharmaceuticals, cosmetics, and food production.

Forensic Science

• Presumptive Blood Tests: Combined with hydrogen peroxide, Phenolphthalein reacts with hemoglobin to produce a pink color, assisting in the identification of bloodstains.

Research and Development

• Used in developing innovative pH-sensitive materials, such as sensors and diagnostic tools.
• Investigated for use in green chemistry applications to replace less sustainable indicators.

Pharmaceutical Testing

• Applied in laboratories to analyze pH-dependent drug formulations and stability tests.

 

Storage Guidelines

• Temperature:
  • Store at a temperature between 15°C and 25°C (59°F to 77°F).
  • Avoid extreme heat, freezing conditions, or fluctuating temperatures.
• Container:
  • Keep in a tightly sealed, corrosion-resistant container (e.g., glass or HDPE).
  • Ensure the container is properly labeled and kept upright to prevent spills.
• Environment:
  • Store in a cool, dry, and well-ventilated area, away from moisture and direct sunlight.
  • Avoid storing near incompatible materials such as strong acids, bases, or oxidizing agents.
• Shelf Life:
  • Long shelf life when stored correctly. Refer to packaging for specific expiration dates.

Handling Guidelines

• Personal Protective Equipment (PPE):
  • Gloves: Wear chemical-resistant gloves (e.g., nitrile or neoprene).
  • Eye Protection: Use safety goggles or a face shield to prevent eye contact.
  • Clothing: Wear a lab coat or protective clothing to prevent skin exposure.
  • Respiratory Protection: Use a dust mask or respirator in poorly ventilated areas or when handling large quantities.
• Work Area:
  • Handle in a well-ventilated space or under a fume hood to prevent inhalation of dust particles.
  • Keep the workspace free of food, drinks, or other non-laboratory items.
• Precautions:
  • Avoid ingestion, inhalation, and skin or eye contact.
  • Wash hands thoroughly after handling, even if gloves are used.
  • Minimize dust generation by handling the powder gently.
• First Aid Measures:
  • Inhalation: Move to fresh air immediately. Seek medical attention if symptoms persist.
  • Skin Contact: Wash thoroughly with soap and water. Remove contaminated clothing.
  • Eye Contact: Rinse eyes with water for at least 15 minutes. Seek medical help if irritation persists.
  • Ingestion: Rinse mouth with water. Do not induce vomiting. Seek medical attention immediately.

Disposal

• Dispose of Phenolphthalein Powder in accordance with local, regional, and national regulations.
• Avoid releasing into the environment. Use a certified chemical waste disposal service if necessary.
