What is p-Dichlorobenzene CAS 106-46-7?

p-Dichlorobenzene is a chlorinated aromatic hydrocarbon with CAS 106-46-7, EC 203-400-5, and molecular formula C6H4Cl2. It is also known as 1,4-dichlorobenzene, para-dichlorobenzene, paradichlorobenzene, or PDB. It is supplied as a white to off-white crystalline solid for industrial use.

What is p-Dichlorobenzene mainly used for?

It is mainly used in industrial deodorant and controlled-volatilization systems, and as a chemical intermediate for dyes, pesticides, specialty chemicals, and sulfur-containing engineering polymer intermediates such as PPS. This product is supplied for industrial processing and further conversion, not as a finished consumer product.

Why does p-Dichlorobenzene gradually volatilize?

p-Dichlorobenzene sublimes under ambient conditions, meaning the solid can pass directly to vapor without first becoming liquid. This controlled sublimation is important in odor-control and deodorant applications. It also means containers should be tightly closed to limit loss during storage.

Which specifications should be checked before ordering?

Confirm supplied form, purity or assay, melting point, moisture, color, and related chlorinated impurities. Because the material is a solid that sublimes, also confirm packaging format, transport classification, and regulatory acceptance for the intended end use and destination.

How should p-Dichlorobenzene be stored and handled?

Store it in tightly closed original containers in a cool, dry, well-ventilated area away from heat, ignition sources, strong oxidizers, and incompatible materials. Use local exhaust ventilation and appropriate PPE during transfer and processing, and minimize vapor or dust exposure.

For a separate para-substituted chlorinated aromatic intermediate, 4-Chlorotoluene is used in different downstream synthesis routes.

Packaging

p-Dichlorobenzene may be supplied in standard industrial packaging suitable for solid chemical transport and storage. Packaging format may vary according to grade, purity requirement, shipment volume, and destination compliance needs.

Storage Conditions

Store in a cool, dry, and well-ventilated area in tightly closed original containers. Keep away from direct heat, strong oxidizing materials, and sources of ignition. Good container sealing is recommended to reduce material loss caused by volatilization or sublimation during storage.

Safety Precautions

Handle in accordance with applicable chemical safety procedures. Avoid prolonged inhalation of vapor or dust and minimize direct skin and eye contact. Appropriate ventilation, personal protective equipment, and safe handling controls should be applied during transfer, processing, and storage. SDS should be reviewed before industrial use.
