In the realm of chemical synthesis and formulation, the precision and reliability of the starting materials are paramount. For compounds like 2-Methoxybiphenyl (CAS 86-26-0), understanding and verifying key specifications ensures that your research, development, or production runs smoothly and yields accurate results. This guide outlines the essential parameters that R&D scientists, product formulators, and procurement specialists should always confirm when looking to buy 2-Methoxybiphenyl.

The Importance of Verification for 2-Methoxybiphenyl (CAS 86-26-0)

As a versatile organic intermediate, 2-Methoxybiphenyl is utilized in a variety of applications, from pharmaceutical synthesis to material science. Deviations in its quality or specifications can lead to unintended side reactions, reduced product yield, purification challenges, or even compromised final product performance. Therefore, diligent verification from your 2-Methoxybiphenyl supplier is non-negotiable.

Critical Specifications to Scrutinize:

  1. CAS Number: The Chemical Abstracts Service (CAS) Registry Number is a unique identifier for chemical substances. For 2-Methoxybiphenyl, this is unequivocally 86-26-0. Always ensure this number is correctly listed on the product label, accompanying documentation, and your purchase order. A mismatch here can indicate a completely different chemical product.
  2. Purity: This is arguably the most critical specification. Purity is typically expressed as a percentage, often determined by Gas Chromatography (GC) or High-Performance Liquid Chromatography (HPLC). For 2-Methoxybiphenyl, common purities offered are ≥97.0% or ≥98.0%. Higher purity grades are generally preferred for sensitive applications like pharmaceutical intermediates to minimize potential interference from impurities. Always check the analytical method used for purity determination.
  3. Appearance: The physical form and color can be indicative of purity and proper handling. For 2-Methoxybiphenyl, expect descriptions such as 'white or colorless to light yellow powder to lump' or 'clear slightly yellow liquid after melting'. Any significant deviation from this description, such as excessive discoloration or the presence of foreign particulate matter, warrants further investigation or rejection of the batch.
  4. Molecular Formula and Molecular Weight: Confirm that the product's molecular formula (C13H12O) and molecular weight (184.23) match the expected compound. This is a basic check that helps confirm the identity of the substance.
  5. Melting Point (MP) and Boiling Point (BP): The reported melting point (30-33°C) and boiling point (274°C) serve as important physical identifiers. Deviations from these ranges can suggest impurities or incorrect product identity.
  6. Certificate of Analysis (COA): This document is provided by the manufacturer and details the specific test results for a particular batch against the established specifications. It should include batch number, manufacturing date, expiry date, and the results of purity tests, appearance, and any other relevant parameters. Always request a COA for the specific lot you receive.

Where to Find Reliable Suppliers

When you purchase 2-Methoxybiphenyl, especially from international markets, it's vital to work with reputable 2-Methoxybiphenyl suppliers and 2-Methoxybiphenyl manufacturers. Companies that are transparent about their specifications, provide comprehensive COAs, and offer responsive technical support are typically reliable. Many manufacturers in China are well-equipped to supply high-quality 2-Methoxybiphenyl, often at competitive prices. Make sure to confirm these specifications before and after receiving your order.

By diligently verifying these key specifications, R&D professionals and formulators can ensure they are using the correct, high-quality 2-Methoxybiphenyl (CAS 86-26-0), paving the way for successful outcomes in their demanding chemical applications.
