Application

HCl can be used:
  • As a catalyst in the synthesis of β-amino ketone in presence of H2O-SDS system by Mannich reaction.[3]
  • In the synthesis of polymer-layered silicate nanocomposites.[4]

Packaging

Supplied in a carbon steel lecture bottle with a CGA180M/CGA110F needle valve installed.

Questions

1–8 of 8 Questions  
  1. 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

  2. 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.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/449/386/product-dating-information-mk.pdf

  3. What type of cylinder does the Product 295426, Hydrogen Chloride, come in?

    1 answer
    1. The Hydrogen Chloride is packaged in a lecture bottle.  The cylinder will be about one foot in length and about two inches in diameter.  For 295426-227G, the valve on the cylinder has a CGA 180M / 110F fitting on it, while DIN 477-1 fittings are found on 295426-230-EU.  The cylinder mass is approximately 1023g (empty) and the valve mass is approximately 206g, giving a total approximate mass of 1229g.  The cylinders are DOT rated (rating is stamped on cylinder).

  7. What equipment is needed to use the Hydrogen Chloride cylinder for Product 295426?

    1 answer
    1. Since Hydrogen Chloride is a corrosive gas, only Stainless Steel or Monel equipment should be used.  For 295426-227G, Monel control valve Z146978 or Monel gas regulators Z406058, Z406066 are recommended.  We would also recommend a Cross Purge Assembly, Z562483 be used in conjunction with the regulators.  A Stainless Steel Hose Barb Adapter Z146838 may also be needed depending on the setup being used.  For 295426-230-EU, regulators Z742162 or Z742164 are recommended.
