General description

Methimazole belongs to the chemical class of thioureylene compounds, used as an anti-thyroid drug in the management of hyperthyroidism.

Application

Beclomethasone dipropionate analytical standard can be used as follows:

  • Silver/graphene-modified carbon-paste electrode (AgGCPE) based electrochemical determination of methimazole
  • Development of a surface-enhanced Raman scattering (SERS) based method to estimate propylthiouracil and methimazole using sodium alginate-protected silver nanoparticles as SERS substrate
  • Detection of methimazole at ultra-trace limits using surface-enhanced Raman spectroscopy based on gold nanoparticles (AuNPs) substrate
  • Quantitative analysis of human blood samples for methimazole using high-performance liquid chromatography-tandem mass spectrometric (HPLC-MS/MS) method
  • Electrochemical determination of methimazole in pharmaceutical tablet and human blood serum samples by molecularly imprinted polymer (MIP)- pencil graphite electrode (PGE) based sensor

Transdermal methimazole is an acceptable alternative to oral treatment for hyperthyroid cats. There are, however, no studies evaluating the duration of T4 suppression after transdermal methimazole application. Such information would be valuable for therapeutic monitoring.

Antithyroid medications are the preferred therapy for the treatment of Graves' disease during pregnancy. Propylthiouracil (PTU) is favored over methimazole (MMI) due to potential teratogenic concerns with MMI. This study was to determine the teratogenic potential of MMI and PTU

Questions

1–2 of 2 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.
