For any B2B procurement professional or R&D scientist in the chemical or pharmaceutical industry, understanding the precise specifications of a chemical intermediate is paramount before making a purchase. 1-Bromo-3-Chloropropane (CAS 109-70-6) is no exception. As a widely used compound in organic synthesis and pharmaceutical manufacturing, its quality directly impacts the success of subsequent reactions and the purity of the final product. This guide outlines the critical specifications you should look for when seeking to buy this essential chemical.
The most fundamental specification is the Assay, which indicates the purity of the compound. For 1-Bromo-3-Chloropropane, a typical high-quality grade is ≥99.50%. This high purity is crucial, especially when the compound is used as a pharmaceutical intermediate, where even minor impurities can lead to unwanted side reactions or compromise the efficacy and safety of the end drug. Always ensure your potential manufacturer or supplier can provide a detailed Certificate of Analysis (CoA) confirming this purity.
The Appearance is another key visual indicator. 1-Bromo-3-Chloropropane is consistently described as a colorless transparent liquid. Any deviation from this, such as a yellow tint or turbidity, might suggest degradation or contamination, and warrants further investigation. Its Melting Point of -59°C and Boiling Point of 144-145°C are also important physical constants that help confirm its identity and purity.
Other critical specifications to consider include Moisture content (typically ≤0.05%) and Color (APHA) (≤20). High moisture content can interfere with certain reactions, particularly those involving moisture-sensitive reagents. Furthermore, understanding the potential Isomer content (≤0.30% is common) is vital, as isomeric impurities can behave differently in synthesis and may not be easily separated. When requesting a quote from a Chinese supplier, always confirm these key parameters to ensure you are sourcing a product that meets your exacting standards.
For those looking to purchase 1-Bromo-3-Chloropropane in bulk, working with a reputable manufacturer that clearly communicates these specifications is vital. This transparency ensures you receive a product that is not only competitively priced but also consistently meets the rigorous demands of your industrial applications.
