Diphenylamine (DPA), ACS Grade

Features:

• Nitrate Sensitivity: Widely utilized in the "Diphenylamine Test" where it reacts with nitrates in a sulfuric acid matrix to produce a deep blue color, sensitive up to 1 part in 1.6 x 10⁶.
• DNA Determination: A primary component of the Dische Test, used to distinguish DNA from RNA and quantify nucleic acids via colorimetry.
• Industrial Application: Serves as a critical stabilizer for smokeless powders by binding nitrogen oxide degradation products.
• NIST-Traceable Quality: Manufactured under rigorous quality control standards to ensure de facto purity for high-precision laboratory applications.

Safety & Handling:

DANGER! Toxic & Environmental Hazard: Harmful if swallowed and causes damage to organs (liver, kidneys, blood) through prolonged exposure. It is very toxic to aquatic life with long-lasting effects.

• Personal Protection: Wear appropriate PPE, including nitrile gloves, safety goggles, and a lab coat. Handle under a chemical fume hood to avoid dust inhalation.
• Storage: Store in a cool, dark place in the original, light-resistant amber glass container. DPA is light-sensitive and will darken upon exposure to UV rays.
• Disposal: Dispose of as hazardous waste in strict accordance with local and federal environmental regulations.
