General description

Benzoic acid melting point standard, 121-123 °C is useful as a melting point calibration standard while defining the purity of pharmaceutical chemicals. Its melting point value is determined with an average of 6 to 12 measurements using a Büchi B-545 instrument that is calibrated against primary standards.

Application

Melting point standard 121-123 °C, benzoic acid is an analytical standard used to calibrate melting point instruments, in the thermodynamic mode of operation. It is also used in R & D labs for chemical quality control (QC) and quality assurance (QA) to identify solid crystalline substances and to check their purity.

Features and Benefits

  • Melting point calibration standard traceable to primary standards (LGC, London)
  • Grade: Analytical Standard
  • Uncertainty of measurement up to ± 0.3 °C
  • Provided with certificates of analysis and safety data sheet
  • A product of analytical standard grade that meets the QC/QA requirements of melting point analysis

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.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/418/501/product-dating-information-06-25-mk.pdf

  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
