General description

λ-Cyhalothrin is a type II highly active synthetic pyrethroid insecticide which contains a-cyano group.[1]

Application

λ-Cyhalothrin is used as an internal standard for the determination of esfenvalerate from water by capillary gas chromatography with electron capture detection.[2]
It may also be used as a pesticide reference standard for the determination of the analyte:
  • In virgin olive oil[3] and cotton[4] by gas chromatography (GC) with electron-capture detection.
  • In leafy vegetables by gas chromatography coupled with an ion trap mass spectrometry detection system (GC–ITMS).[5]

Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

Questions

1–3 of 3 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.

  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

  3. HOW LONG SHOULD IT BE STORED?

    1 answer
    1. Each lot of this product is assigned a firm expiration date of approximately 5 years. It can be stored at room temperature for this period. The lot specific expiration date can be found on the label as well as the Certificate of Analysis.
