Questions

  1. Hello, Is it possible to get o-cresol in liqudi form?

    1 answer
    1. While the physical form of this product is not a specification, the material may present as a liquid or a solid. The melting point of this compound is approximately 31°C, gentle warming will re-liquify the product without harming the quality.
      There are other o-Cresol product options available that report the physical form on a lot-specific basis. This information is available in the product Certificate of Analysis. Please see the following links to review these products:
