Description

Nitrogen Dioxide CAS NO 10102-44-0 is a critical industrial gas and a significant chemical intermediate. Its primary importance lies in its role as a precursor in the large-scale synthesis of nitric acid, a fundamental building block for fertilizers and explosives. This reddish-brown gas is essential for industries ranging from chemical manufacturing and metallurgy to environmental testing and advanced materials research.

Application

• Nitric Acid Production: The primary industrial use, serving as an intermediate in the Ostwald process for manufacturing nitric acid (HNO₃).
• Chemical Synthesis: Acts as a potent nitrating and oxidizing agent in organic chemistry for producing nitro compounds, dyes, and pharmaceuticals.
• Rocket Propellant: Utilized as an oxidizer in certain bipropellant rocket fuel systems.
• Catalyst & Intermediate: Used in catalyst systems and as a reactive intermediate in various specialty chemical processes.
• Metallurgy: Employed in metal treatment and etching processes.
• Laboratory Reagent: Serves as a calibrated standard and reactive agent in analytical and research laboratories.
• Pollution Control & Calibration: Used in environmental monitoring as a calibration gas for NOx analyzers and in studies of atmospheric chemistry.

Quality Control

Our Nitrogen Dioxide is produced and handled under stringent quality management protocols to ensure batch-to-batch consistency and reliability. We provide detailed Certificates of Analysis (COA) for each lot, which include key parameters such as assay/purity and specific impurity profiles. Our quality systems are designed to meet the exacting standards required for industrial chemical synthesis and technical applications.

Storage

Preserve in a tightly closed, approved specialty gas cylinder, stored in a cool, well-ventilated area. Due to its gaseous, toxic, and oxidizing nature, cylinders must be secured upright and protected from physical damage, heat, and direct sunlight. Storage areas must be separate from combustible materials and reducing agents. Always use appropriate gas handling equipment and follow all local and international regulations (e.g., OSHA, GHS) for hazardous materials.
