In the realm of chemical sourcing, particularly for intermediates destined for pharmaceutical or advanced material applications, understanding and verifying product specifications is non-negotiable. 3-Methoxybenzyl Chloride (CAS 824-98-6) is no exception. For procurement professionals and chemists alike, knowing what quality parameters to scrutinize is vital. This guide, drawing from the expertise of manufacturers like NINGBO INNO PHARMCHEM CO.,LTD., outlines the key specifications to consider when you buy 3-methoxybenzyl chloride.

Key Specifications for 3-Methoxybenzyl Chloride

When evaluating a potential supplier or manufacturer for 3-Methoxybenzyl Chloride, pay close attention to the following:

  1. Assay/Purity: This is arguably the most critical specification. High-purity 3-Methoxybenzyl Chloride typically has an assay of 97% or, more ideally, 99% minimum. For demanding applications like API synthesis, higher purity is often preferred to minimize side reactions and ensure product integrity. Always request a Certificate of Analysis (CoA) that details the purity and the analytical method used (e.g., GC or HPLC).
  2. Appearance: The product is usually described as a “clear colorless to light yellow liquid.” Any significant deviation from this description, such as cloudiness or a dark color, might indicate contamination or degradation.
  3. CAS Number: While seemingly basic, always confirm the CAS number is correct (824-98-6) to ensure you are obtaining the exact compound you need.
  4. Molecular Formula and Weight: C8H9ClO and a molecular weight of 156.61 g/mol are standard identifiers.
  5. Moisture Sensitivity: Sources indicate this compound is moisture-sensitive. Proper storage and handling information should be available from the supplier, and you should expect robust packaging to maintain product integrity.
  6. Storage Temperature: Recommendations often suggest storage between 2-8°C. This is a crucial handling parameter that indicates stability considerations.
  7. Other Properties: Information on melting point (though it's a liquid at room temperature, it has a melting point around 101.67°C listed in some contexts, which might refer to a solid precursor or related form), boiling point (124°C at 13 mm Hg), density (1.078 g/mL at 25°C), and refractive index are also important for quality verification and application suitability.
