一般說明

Mercury (quicksilver) is a rare chemical element found most commonly in cinnabar (HgS). It is widely employed in the production of industrial chemicals like mercuric (I) and mercuric (II) compounds, because of two oxidation states (+1 and +2). Additionally, it is also used in the synthesis of coordination complexes of mercury as well as organomercury compounds. Mercury(II) salts are used in the preparation of industrially important chemical reagents such as Millon′s base, Nessler′s reagent (potassium tetraiodomercurate), one-dimensional polymer (salts of HgNH2+)n), etc.

The adipocytokines, leptin, adiponectin, and interleukin-6, which stimulate liver C-reactive protein (CRP) production, are regarded as potential candidate intermediates between adipose tissue and overweight-induced hypertension. We examined the associations between leptin, adiponectin, and CRP levels with both prevalent and 5-year

Questions

1–4 of 4 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. I see that Mercury is sold by weight, but it's a liquid. What is the volume?

    1 answer

    1. The specific gravity of liquid mercury at 20°C is 13.546, according to the CRC Handbook of Chemistry and Physics, 82nd ed. (2001-2002), page 4-19. We list several mercury products, in various package sizes, sold by weight. Here are the conversions from mass to volume: 5G = 0.37 mL. 50G = 3.7 mL. 100G = 7.4 mL. 250G = 18.5 mL. 500G = 36.9 mL. 2KG = 147.6 mL.
