Description

n-(1-Naphthyl) Ethylenediamine Oxalate is a high-purity organic salt derivative of ethylenediamine, widely recognized as a critical reagent and intermediate in analytical chemistry and pharmaceutical synthesis. Its primary value lies in its role as a chromogenic agent for the spectrophotometric determination of nitrite and nitrate ions, ensuring precise and reliable analytical results. This compound is essential for research laboratories, quality control facilities in the food and water treatment industries, and manufacturers of diagnostic kits and fine chemicals.

Application

• Spectrophotometric Reagent: Key chromogenic component in Griess-type assays for the colorimetric detection and quantification of nitrite (NO₂⁻) and nitrate (NO₃⁻) ions in environmental, food, and clinical samples.
• Pharmaceutical Intermediate: Serves as a building block in the synthesis of more complex molecules, including certain dyes and potential active pharmaceutical ingredients (APIs).
• Water Quality Analysis: Used in test kits and standard methods for monitoring nitrite levels in drinking water, wastewater, and agricultural runoff.
• Food Safety Testing: Employed in analytical procedures to measure residual nitrite/nitrate levels in cured meats, vegetables, and other food products.
• Research & Development: A valuable tool in biochemical and environmental research for studying nitrogen cycle processes and oxidative stress markers.
• Diagnostic Manufacturing: Incorporated into the production of clinical diagnostic strips and reagents for urinalysis and other bodily fluid tests.

Quality Control

Our n-(1-Naphthyl) Ethylenediamine Oxalate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for analytical and research applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture.
