N N-Diethyl-p-phenylenediamine sulfate CAS 6283-63-2
N N-Diethyl-p-phenylenediamine sulfate Description
The Core Features and Applications of N-Diethyl-phenylenediamine Sulfate (DPD Reagent)
N N-Diethyl-p-phenylenediamine sulfate (CAS 6283-63-2) presents as a highly refined white to off-white crystalline powder with a molecular structure of \(C_{10}H_{16}N_2 \cdot H_2SO_4\) and a mass of 262.33. This chemical matrix features a verified melting threshold of 184–186°C and dissolves smoothly within water and alcohol environments.
Because the crystal lattice reacts sharply when exposed to direct light or ambient air, logistics teams must keep the material hermetically sealed inside dark, light-shielded containers. For precise formulation work, a standard 5% aqueous solution of this sulfate salt yields a distinct acidic pH window of roughly 2.0–2.2, while the baseline purity specification typically tracks at \(\ge \)98.0%.
Within modern analytical chemistry, laboratory technicians widely recognize this compound as the active backbone of DPD reagent setups. It functions as the frontline chromogenic indicator for mapping free and total chlorine concentrations inside municipal water grids and wastewater treatment systems.
The molecule works by triggering an instant, quantifiable color shift upon reacting with active chlorine fractions, enabling precise photometric tracking. Beyond environmental monitoring, pharmaceutical analysts utilize the salt to drive spectrophotometric assays for identifying target drugs rich in aromatic amines and phenolic hydroxyl groups. Furthermore, the chemical anchors a major market share in traditional photographic emulsion chemistry, where film labs utilize it as the CD-1 color developer.

Scalable Supply Chain & Stock Capacity
Through close integration with fully certified chemical manufacturing assets, we guarantee a highly stable, audit-ready production pipeline for N-Diethyl-phenylenediamine Sulfate. Our standard commercial grade maintains a strict purity threshold of \(\ge \)98.0%, verified through high-performance liquid chromatography (HPLC) and multi-stage neutralization titration loops. To eliminate procurement friction, our quality control team runs exhaustive pre-shipment checks on the following critical batch-release markers:
- Physical Appearance: White to off-white refined crystalline powder
- Melting Threshold: 184–186°C matrix integrity
- Loss on Drying: \(\le \)5.0% maximum water cap
- Aqueous pH (5% solution): Acidic window of 2.0–2.2
We partition our inventory to serve diverse commercial roadmaps, bottleneck-free. For laboratory trials and assay development, we offer standalone 25g, 100g, and 500g amber bottle configurations. Small-scale R&D orders clear our transit dock within 24 to 48 hours, while major tonnage campaigns are palletized and dispatched within 5 to 7 business days.
Technical Liaison & Quality Validation
Every single container leaves our facility backed by an official, lot-specific Certificate of Analysis (COA) documenting actual purity, moisture thresholds, and crystalline ranges. Because our in-house application engineers understand exactly how this sulfate salt behaves in water-quality chlorine spectrophotometry and pharmaceutical assay tracking, they can directly assist your lab during vendor qualification and spec alignment.
To defend the powder from premium-tier degradation, store the chemical tightly sealed in a bone-dry warehouse maintained at standard ambient room temperatures of 15–25°C (59–77°F). It is vital to isolate the stock far from strong oxidizing reagents and direct UV exposure. Under this strict containment protocol, the product maintains complete chemical integrity over a 24-month shelf life.

FAQ
It serves as the global commercial benchmark for environmental water monitoring and chemical asset tracking. Analysts rely on the compound as the core colorimetric indicator to map exact free and total chlorine concentrations inside municipal water networks and wastewater treatment plants. Upon contact with active chlorine fractions, it triggers an instant, highly predictable shift to a magenta Wurster dye intermediate for precise spectrophotometric quantification. Beyond water testing, pharmaceutical quality control labs utilize the chemistry to drive photometric assays for identifying target drug compounds rich in aromatic amines and phenolic hydroxyl groups.
Yes, they share the exact same chemical identity under CAS 6283-63-2. While environmental engineers track it as a free chlorine indicator, historical and specialty film laboratories utilize the exact same p-phenylenediamine derivative as the N N-Diethyl-p-phenylenediamine sulfate . In photographic emulsion lines, its oxidized form links with embedded color couplers to form permanent image dyes
