Our High Quality 1,3-Dichlorobenzene (CAS 541-73-1) is a well - recognized chemical product in the market. It comes with a very competitive price, combining high quality and cost - effectiveness.
**Chemical Formula**: C₆H₄Cl₂. The molecular weight is approximately 147.00 g/mol. It is a colorless to light yellow liquid with a distinct aromatic odor. The boiling point ranges from 172 - 173 °C, and the melting point is around -24 °C. It has a density of about 1.288 g/cm³ at 20 °C. This product is insoluble in water but soluble in many organic solvents such as ethanol, ether, and benzene.
1. **Chemical Synthesis**: 1,3 - Dichlorobenzene serves as an important intermediate in the synthesis of various chemicals. It can be used in the production of pesticides, dyes, and pharmaceutical products. For example, in the pesticide industry, it can be further processed into more complex pesticide compounds with high - efficiency pest - control properties.
2. **Solvent**: Due to its good solubility in organic substances, it is used as a solvent in some industrial extraction and reaction processes. It can help dissolve and disperse other substances evenly, promoting chemical reactions to proceed smoothly.
3. **Fragrance and Repellent**: It has a certain odor - related property. In some cases, it can be used in the preparation of fragrances or as a component in insect repellents.
When using High Quality 1,3 - Dichlorobenzene, it is necessary to follow strict safety procedures.
1. **Storage**: Store the product in a cool, dry, and well - ventilated area. Keep it away from sources of ignition and heat, as it is flammable. It should be stored in a tightly closed container to prevent leakage and evaporation.
2. **Handling**: Wear appropriate personal protective equipment such as gloves, safety glasses, and a lab coat. Avoid direct contact with the skin, eyes, and inhalation of its vapors. If contact occurs, immediately rinse the affected area with plenty of water and seek medical attention if necessary.
3. **Dosage and Mixing**: When using it in chemical reactions, carefully calculate the dosage according to the reaction requirements. When mixing with other substances, add it slowly and stir evenly to ensure a stable reaction.
**Case 1: Pesticide Synthesis**
In a certain chemical plant, they were producing a new type of pesticide. They used 1,3 - Dichlorobenzene as a key intermediate. First, they dissolved 1,3 - Dichlorobenzene in an appropriate organic solvent under controlled temperature and stirring conditions. Then, they added specific reaction reagents step - by - step. After a series of complex chemical reactions, purification, and separation processes, they successfully obtained the target pesticide product. This pesticide showed excellent pest - control effects in field tests, and the yield of crops using this pesticide increased significantly.
**Case 2: Solvent in Extraction Process**
A laboratory was conducting an extraction experiment to obtain a specific natural product from a plant sample. They used 1,3 - Dichlorobenzene as the extraction solvent. By soaking the plant sample in 1,3 - Dichlorobenzene for a certain period and then performing filtration and evaporation operations, they were able to efficiently extract the target natural product. The purity of the extracted product was relatively high, which was beneficial for subsequent research and development work.
