For research and development scientists, the precise characteristics of chemical compounds dictate the success of their experiments. 3,4-Dichlorophenyl Isothiocyanate (CAS: 6590-94-9) is a chemical intermediate that demands a thorough understanding of its physical and chemical properties. As a specialized reagent, its performance in organic synthesis and as a building block for novel compounds is directly tied to its quality and consistent specifications. When seeking to buy this compound, R&D professionals must prioritize suppliers who clearly detail these attributes.
The appearance of 3,4-Dichlorophenyl Isothiocyanate is typically described as an orange-yellow transparent liquid. This visual cue is important, but the core technical specification for R&D is its assay, which is consistently reported as ≥99.0%. This high level of purity is crucial for minimizing side reactions and ensuring the desired product yield and purity in complex multi-step syntheses. A manufacturer or supplier that provides a detailed Certificate of Analysis (CoA) confirming this purity is a valuable partner for any research laboratory.
Beyond appearance and purity, understanding other physical properties is also beneficial. Information such as density (e.g., 1.422 g/mL at 25 °C) and boiling point (e.g., 134-136 °C at 7 mm Hg) can inform handling, storage, and reaction parameter optimization. For scientists needing to calculate reaction stoichiometry or prepare specific molar concentrations, having access to the precise molecular weight (204.07600) and CAS number (6590-94-9) is non-negotiable. This data is fundamental when sourcing from any reputable chemical supplier.
The role of 3,4-Dichlorophenyl Isothiocyanate as a chemical intermediate means its reactivity and stability are key considerations. It's often stored under specific conditions, such as under inert gas (nitrogen or Argon) at 2-8°C, to maintain its integrity, especially if it is moisture-sensitive. Research chemists often look for suppliers who provide clear guidance on handling and storage to maximize the shelf-life and efficacy of the material. When evaluating a potential manufacturer, consider their expertise in producing and supplying such reactive intermediates consistently.
In summary, for R&D scientists, a detailed understanding of 3,4-Dichlorophenyl Isothiocyanate's properties – from its vibrant appearance to its high assay and specific handling requirements – is essential for successful experimental design. Partnering with a reliable supplier who provides comprehensive technical data facilitates efficient and effective research outcomes.
