General description

Potassium clavulanate is an oxapenam derivative and belongs to the group of β-lactamase inhibitors. It is used in combination with the penicillin group of antibiotics to give them resistance to β-lactamase.

Application

The analytical standard can be used as follows:
  • Simultaneous analysis of amoxicillin and clavulanate potassium in pharmaceutical formulations by capillary electrophoresis (CE) combined with capacitively coupled contactless conductivity detection (C4D)
  • Development of a stability-indicating high-performance liquid chromatographic (HPLC) method combined with mass spectrometry (MS) to measure amoxicillin, clavulanate potassium, and their impurities in their combined dosage forms
  • Residue analysis of potassium clavulanate and amoxicillin trihydrate by a UV spectrophotometric method in their bulk, combined tablet formulations, and human urine samples
  • HPLC method-based determination of meropenem and potassium clavulanate in the presence of their degradation impurities in intravenous solutions in combination with a diode array detector (DAD)
  • Determination of amoxicillin and clavulanic acid by capillary zone electrophoresis (CZE) in their combined commercial formulations

Biochem/physiol Actions

β-lactamase inhibitor, typically added to amoxicillin to increase its effectiveness.

Questions

1–3 of 3 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. Hello! I would like to know if there is any specification relating to what solvent I should use with this product? And if so, if you have it available. Thank you.

    1 answer

    1. This product is not tested for solubility. However, it is reportedly soluble in water, ethanol, methanol, DMSO, and dimethylformamide. It may be beneficial to store solutions prepared in water under inert gas.
