M-dinitrobenzene – 500 gram Packs

M-dinitrobenzene, also known as 1,3-dinitrobenzene, is an aromatic organic compound bearing two nitro groups in the meta positions of a benzene ring. Its molecular formula is C6H4N2O4 and its molecular mass is about 168.11 g/mol. It is generally a pale yellow crystalline solid with low water solubility. The strong electron-withdrawing nature of its nitro substituents makes the compound relevant to aromatic electronic effects, spectroscopy and controlled chemical analysis. It is also a hazardous substance that can cause systemic toxicity through exposure, so routine unsupervised classroom use is inappropriate. In advanced educational and research settings, it may be studied through approved analytical or mechanistic procedures with carefully selected controls, ventilation and waste management. This listing is for the 500 gram pack size.

Frequently Asked Questions About M-dinitrobenzene

What does the m in m-dinitrobenzene mean?

The prefix m stands for meta, indicating that the two nitro groups occupy the 1 and 3 positions on the benzene ring. This arrangement is distinct from ortho- and para-dinitrobenzene, which have different structures and properties.

What is the molecular formula and CAS number?

The molecular formula of 1,3-dinitrobenzene is C6H4N2O4, and the molecular mass is approximately 168.11 g/mol. Its empirical formula reduces to C3H2NO2. The CAS Registry Number for this specific positional isomer is 99-65-0.

Is m-dinitrobenzene readily soluble in water?

No. 1,3-Dinitrobenzene has low water solubility. Solvent selection for analytical work should follow an established method and the relevant Safety Data Sheet; do not assume it can be prepared as a concentrated aqueous solution.

Why are strict handling controls necessary?

M-dinitrobenzene can be absorbed through the skin and can cause serious systemic effects, including interference with normal blood oxygen transport. Trained personnel should use effective ventilation, compatible gloves and eye protection while preventing contamination and following workplace exposure controls.

Can this compound be used in school practicals?

Because of its toxicity, m-dinitrobenzene is not appropriate for casual or unsupervised school demonstrations. Specialist or advanced teaching use requires an institutional risk assessment, suitable containment, trained supervision and appropriate disposal arrangements.

Storage Conditions for M-dinitrobenzene

Store m-dinitrobenzene in a tightly closed, clearly identified container in a cool, dry and well-ventilated designated chemical-storage area. Protect it from excessive heat, ignition sources and contact with strong oxidizing agents, strong bases and incompatible reducing materials. Restrict access to trained personnel and segregate it from materials intended for routine student use.

Precautions for Handling M-dinitrobenzene

Consult the current Safety Data Sheet and institutional exposure procedures before handling m-dinitrobenzene. Its dust and skin absorption create significant risks, so use an appropriate fume hood, suitable chemical-resistant gloves, protective clothing and eye protection. Prevent inhalation, spills and contamination of work surfaces. Avoid uncontrolled heating or reactions with incompatible substances. Collect waste as hazardous organic chemical waste and follow emergency protocols if exposure occurs.
