For professionals in the chemical and materials industries, a thorough understanding of chemical properties and safe handling procedures is fundamental to successful operations. 4-Chloromethyl Styrene (CAS 1592-20-7), a vital monomer for advanced polymer synthesis, requires specific attention to its characteristics. As a leading supplier and manufacturer of this chemical, we are dedicated to providing essential insights to aid procurement managers and R&D scientists in making informed decisions when they choose to buy 4-Chloromethyl Styrene.

The physical appearance of 4-Chloromethyl Styrene is typically described as a clear yellow liquid, though some sources may list it as colorless. Its molecular formula is C9H9Cl, with a molecular weight of 152.62 g/mol. A critical aspect for users is its reactivity, stemming from both the vinyl and the chloromethyl functional groups. Due to the inherent instability of vinyl monomers, 4-Chloromethyl Styrene is often stabilized with inhibitors like t-butylcatechol (TBC) to prevent spontaneous polymerization during storage and transport. Purity levels are commonly specified as ≥97% or ≥98%, with common impurities being other isomers or related compounds, so verifying these specifications from your supplier is essential.

Proper storage of 4-Chloromethyl Styrene is crucial to maintain its quality and prevent degradation. It is typically recommended to store this chemical under refrigeration, around 4°C, in a cool, dry, and well-ventilated area. Protection from light and air is also advised. Storing under an inert atmosphere, such as nitrogen, further helps to preserve its stability and purity. When inquiring about purchasing this product from manufacturers in China, clarify the recommended storage conditions to ensure optimal product integrity upon arrival at your facility.

Handling 4-Chloromethyl Styrene necessitates strict adherence to safety protocols. As an alkylating agent, it is classified as corrosive and an irritant. Direct contact with skin and eyes can cause severe burns. Inhalation of vapors can lead to respiratory tract irritation and potential sensitization. Therefore, appropriate personal protective equipment (PPE) is mandatory. This includes chemical-resistant gloves (e.g., nitrile or neoprene), safety goggles with side shields or a full face shield, and protective clothing. Work should always be conducted in a well-ventilated area, preferably within a chemical fume hood. It is also important to avoid ingesting or inhaling the substance. For any spills or accidental releases, immediate containment and cleanup using inert absorbent materials are required, followed by proper disposal as hazardous waste.

As a reputable manufacturer and supplier, we provide comprehensive documentation, including Safety Data Sheets (SDS), which detail all necessary safety information.
