Description

Dinitrotoluene CAS NO 25321-14-6 is an important aromatic nitro compound, primarily existing as a mixture of isomers, with 2,4-dinitrotoluene and 2,6-dinitrotoluene being the most significant. This compound serves as a critical intermediate in the synthesis of toluene diisocyanate (TDI), a fundamental building block for polyurethane foams and elastomers. It is essential for manufacturers in the polyurethane, chemical synthesis, and specialty materials industries requiring a reliable and high-purity precursor.

Application

• Primary precursor for Toluene Diisocyanate (TDI) production, a key component in flexible and rigid polyurethane foams.
• Intermediate in the manufacture of dyes, pigments, and organic colorants.
• Used in the synthesis of explosives and propellants, subject to strict regulatory controls.
• Employed as a chemical intermediate for agricultural chemicals and pharmaceutical compounds.
• Component in corrosion inhibitors and specialty chemical formulations.
• Research and development applications in organic synthesis and material science.

Quality Control

Our Dinitrotoluene is manufactured under stringent process controls to ensure batch-to-batch consistency and high purity. Quality is verified through comprehensive analytical testing, including isomer distribution analysis, purity assays, and impurity profiling. Certificates of Analysis (COA) detailing all specifications are provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat, sparks, and open flame. Due to its properties of being easily oxidized, storage under an inert atmosphere such as nitrogen is recommended for long-term stability. Keep away from strong reducing agents, strong bases, and combustible materials. Recommended storage temperature: 15-25°C.
