Diphenylamine- 1 Kg Packs

Diphenylamine is an aromatic secondary amine consisting of two phenyl groups attached to a nitrogen atom. It has the molecular formula C₁₂H₁₁N and a molecular weight of approximately 169.22 g/mol. This organic compound is generally encountered as a colourless to pale brown crystalline solid and exhibits limited solubility in water. Its aromatic structure and chemical reactivity make it useful in selected analytical chemistry procedures, oxidation-related investigations, and studies involving organic reaction mechanisms. Diphenylamine is also used as an indicator reagent in certain analytical methods, including specialised oxidation–reduction procedures where the method specifies its use. It is relevant to university chemistry practicals, analytical laboratories, and research facilities requiring an appropriate aromatic amine reagent. Because Diphenylamine can be hazardous through inhalation, ingestion, and skin contact, it must be handled using suitable protective equipment and established laboratory safety procedures. Lab Wale offers Diphenylamine in 1 kg packs for appropriate laboratory applications.

Frequently Asked Questions About Diphenylamine

What is Diphenylamine used for in laboratories?

Diphenylamine is used in selected analytical procedures, oxidation–reduction investigations, and organic chemistry research. Certain methods employ it as an indicator reagent, while other procedures use it in studies of aromatic amine reactivity. Its suitability depends on the specific analytical method, reagent formulation, and laboratory requirements.

What is the molecular formula and molecular weight of Diphenylamine?

Diphenylamine has the molecular formula C₁₂H₁₁N and a molecular weight of approximately 169.22 g/mol. Its empirical formula is also C₁₂H₁₁N because the atom ratio cannot be reduced to a smaller whole-number ratio. These values identify the neutral Diphenylamine compound.

What is the CAS number of Diphenylamine?

The CAS Registry Number for Diphenylamine is 122-39-4. This identifier distinguishes the compound from related aromatic amines and other nitrogen-containing organic substances. Confirm the chemical identity and required grade before purchasing or using it in a laboratory procedure.

Is Diphenylamine suitable for educational and research laboratories?

Diphenylamine may be used in appropriately equipped college, university, analytical, and research laboratories when the procedure requires this reagent. Because it presents significant health hazards, its use should be risk-assessed and supervised where appropriate. The selected grade must meet the requirements of the intended method.

How should Diphenylamine be stored and handled safely?

Store Diphenylamine in a tightly closed, compatible container in a cool, dry, well-ventilated location, protected from incompatible substances. Avoid inhalation and contact with the skin or eyes. Wear suitable protective gloves, clothing, and eye protection, minimise dust generation, and follow the applicable Safety Data Sheet and institutional procedures for spills and disposal.

Storage Conditions for Diphenylamine

Store Diphenylamine in a tightly closed, compatible container in a cool, dry, well-ventilated area, protected from excessive heat and direct light. Keep it away from strong oxidising agents and strong acids, which can cause hazardous reactions. Maintain appropriate chemical segregation, prevent environmental release, and follow the supplier’s storage instructions and applicable institutional chemical-storage procedures.

Precautions for Handling Diphenylamine

Review the applicable Safety Data Sheet before handling Diphenylamine. Wear suitable chemical-resistant gloves, protective clothing, and safety goggles, and use appropriate ventilation to minimise exposure to dust. Avoid inhalation, ingestion, and skin or eye contact. Keep the material away from incompatible chemicals and ignition sources, and prevent releases into drains or the environment. Manage spills and dispose of contaminated materials through approved hazardous chemical-waste procedures.
