DPD (N,N-Diethyl-p-phenylenediamine) Solution
Manufacturer: LabChem Inc.
DPD (N,N-Diethyl-p-phenylenediamine) Solution from LabChem Inc. is a high-precision analytical reagent used for the colorimetric determination of Free and Total Residual Chlorine, as well as Chlorine Dioxide. When added to a water sample, the DPD reacts instantaneously with oxidizing agents to produce a red/pink tint, the intensity of which is proportional to the disinfectant concentration.

Lead Times May Vary.
Features:
- High Sensitivity: Capable of detecting residual chlorine at concentrations as low as 0.01 mg/L, essential for municipal water safety and wastewater compliance.
- Rapid Response: Provides an immediate color shift for quick-turnaround testing in industrial cooling towers, pools, and drinking water facilities.
- Optimized Stability: Formulated by LabChem to minimize the rapid oxidation common with DIY-prepared DPD solutions.
- Amber Packaging: Provided in light-resistant bottles to protect the reagent from UV-induced degradation.
Safety & Handling:
WARNING! Acidic & Light Sensitive: This solution is stabilized with acid and is sensitive to air and light. It may cause skin and eye irritation.
- Personal Protection: Wear nitrile gloves, safety goggles, and a lab coat. Handle in a well-ventilated area.
- Storage: Store in a cool, dry place ($15\text{--}25$°C). Keep the bottle tightly closed and away from direct sunlight. Discard the solution if it turns dark pink or brown, as this indicates reagent exhaustion.
- Interference Warning: High concentrations of oxidized manganese or iodine may interfere with readings.
