For any industrial chemical, quality assurance is not just a benchmark but a prerequisite for safety, efficacy, and consistent performance. (2,2-Dichlorocyclopropyl)benzene (CAS 2415-80-7), a crucial organic intermediate, demands rigorous quality control throughout its production and supply chain. Manufacturers are responsible for ensuring that this compound, characterized by its molecular formula C9H8Cl2, meets stringent standards for its intended applications, primarily in pharmaceutical synthesis.

Key Quality Parameters for (2,2-Dichlorocyclopropyl)benzene

Manufacturers typically adhere to specific quality parameters when producing (2,2-Dichlorocyclopropyl)benzene. The most critical is purity, often specified as a minimum assay of 98.0% or, ideally, 99%. This high level of purity is vital for preventing side reactions and ensuring the integrity of downstream products, such as ciprofibrate. Other important quality indicators include:

  • Appearance: A clear, colorless to very slightly yellow liquid ensures the absence of significant contamination.
  • Identification: Analytical techniques like HNMR and IR spectroscopy are used to confirm the compound's structure.
  • Physical Properties: Consistent density and melting point data (where applicable) are essential for process engineers.

These parameters are detailed in technical data sheets (TDS) provided by the manufacturer. Ensuring these specifications are met is fundamental for any buyer intending to purchase this chemical.

The Manufacturer's Role in Quality Assurance

Reputable manufacturers of (2,2-Dichlorocyclopropyl)benzene invest heavily in quality assurance protocols. This includes:

  • Raw Material Testing: Ensuring the quality of starting materials like styrene and other reagents.
  • In-Process Monitoring: Implementing checks during the synthesis to control reaction parameters and identify potential deviations.
  • Final Product Analysis: Comprehensive testing of each batch before it is released for sale.
  • Packaging and Storage: Utilizing appropriate packaging (e.g., 200kg drums) and storage conditions to maintain product integrity during transport and storage.

When considering a purchase, it's beneficial to inquire about the manufacturer's quality management system and certifications. For instance, asking about their compliance with ISO standards or their internal quality control processes can provide assurance.

Safe Handling and Regulatory Compliance

Beyond chemical purity, safety data sheets (SDS) are critical for understanding the safe handling, storage, and disposal of (2,2-Dichlorocyclopropyl)benzene. Manufacturers must provide accurate SDS to inform users about potential hazards and necessary precautions. Compliance with relevant chemical regulations is also a cornerstone of quality assurance.

In conclusion, the quality assurance of (2,2-Dichlorocyclopropyl)benzene from manufacturers is multifaceted, encompassing purity, structural confirmation, physical properties, and safe handling. By prioritizing these aspects, buyers can secure a reliable intermediate for their demanding industrial applications.
