Diphenylamine – 500 gram 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 occurs as a crystalline solid and has limited solubility in water, while dissolving in several organic solvents. Its chemical structure and oxidation-related reactivity make it useful in selected analytical chemistry procedures, redox indicator systems, and organic chemistry investigations. Diphenylamine is employed in appropriate laboratory methods involving oxidation–reduction reactions and studies of aromatic amine chemistry. It is relevant to university chemistry practicals, analytical laboratories, and research facilities where the compound’s properties meet the experimental requirements. As Diphenylamine can present significant health and environmental hazards, it requires suitable protective equipment, appropriate ventilation, and responsible chemical waste management. Lab Wale offers Diphenylamine in 500 gram packs for suitable laboratory and research 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 use it as an indicator reagent, while other applications involve studies of aromatic amine reactivity. Its suitability depends on the validated 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 constituent atom ratio cannot be reduced to a smaller whole-number ratio. These values apply to 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 can be used in appropriately equipped college, university, analytical, and research laboratories when the procedure requires this reagent. Its hazards require a suitable risk assessment, appropriate protective measures, and trained supervision where necessary. 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. 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 chemical segregation, 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 segregated from strong oxidising agents and other incompatible substances identified in the applicable Safety Data Sheet. Prevent environmental release, maintain clear labelling, and follow the supplier’s storage instructions and 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 dust exposure. Avoid inhalation, ingestion, and skin or eye contact. Prevent releases into drains or the environment, and manage spills and contaminated materials through approved hazardous chemical-waste procedures in accordance with institutional requirements.
