Description générale

1,2-Dihydroxybenzene (a phenolic compound)[1] is a useful industrial chemical.[2] It is an ortho isomeric form of dihydroxybenzene.[3] It is commonly referred to as catechol or pyrocatechol. Its standard molar enthalpy of combustion and sublimation at 298.15K have been evaluated by static-bomb calorimetry and microcalorimetry, respectively.[4]

Application

1,2-Dihydroxybenzene may be used as raw material for the industrial synthesis of rubber, dyes, plastics, pharmaceuticals and cosmetics.[3]
1,2-Dihydroxybenzene in combination with amberlite XAD-2, can be used as a chelating resin in the determination of metal ions, using atomic absorption spectrophotometry (AAS).[5]

Questions

1–2 of 2 Questions  

  1. How can I determine the shelf life / expiration / retest date of this product?

    1 answer

    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

  2. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer

    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf
