NINGBO INNO PHARMCHEM CO.,LTD. is pleased to offer a technical examination of 1,3-Dichloropropene (CAS 542-75-6), focusing on its intricate chemistry and the factors that make it a valuable compound. Understanding the 1,3-Dichloropropene chemical properties is fundamental for its effective use in various industries.

The molecular formula for 1,3-Dichloropropene is C3H4Cl2, and it exists as cis and trans isomers. The provided CAS number, 542-75-6, commonly refers to the mixture or specifically the trans isomer, which is often more industrially relevant. Its molecular weight is approximately 110.97 g/mol. This chlorinated alkene features a double bond and two chlorine atoms, lending it specific reactivity that is leveraged in its applications. The presence of the double bond makes it susceptible to addition reactions, while the chlorine atoms influence its polarity and stability.

The physical characteristics of 1,3-Dichloropropene are also key to its handling and application. It is typically a colorless liquid with a distinct, sharp odor. Its boiling point is around 108.4 °C at standard atmospheric pressure, and it has a flash point of approximately 27.8 °C, indicating its flammability. Its density is about 1.175 g/cm³. It is generally insoluble in water but miscible with many organic solvents, which is a common trait for halogenated hydrocarbons.

While not directly detailed in all sources, the synthesis of 1,3-Dichloropropene often involves the chlorination of propylene or related hydrocarbons. The specific process can influence the ratio of cis and trans isomers produced. For industries requiring specific isomer ratios or high purity, sourcing from specialized 1,3-Dichloropropene manufacturers like NINGBO INNO PHARMCHEM CO.,LTD. is crucial. These manufacturers possess the expertise and infrastructure to control synthesis parameters and ensure product quality.

The applications of 1,3-Dichloropropene, primarily as a soil fumigant in agriculture and as a component in electronic chemicals (e.g., photoresists), are directly linked to its chemical structure and reactivity. Its ability to act as a fumigant relies on its volatility and biocidal properties, while its use in electronics is often related to its performance as a solvent or reactant in specific formulation processes. Understanding these uses of 1,3-Dichloropropene helps in appreciating its industrial significance.

For any professional working with 1,3-Dichloropropene, accessing comprehensive 1,3-Dichloropropene safety data is imperative. This includes understanding its hazard symbols (Toxic, Dangerous, Harmful, Flammable) and transport information (UN 1992). NINGBO INNO PHARMCHEM CO.,LTD. ensures that customers receive accurate safety documentation, supporting responsible chemical management.
