General description

2-Chloro-4,6-dimethoxy-1,3,5-triazine is a stable, yet highly reactive, peptide coupling agent.[1] It is reported as useful coupling reagent for the purification of peptides.[2] Catalytic amide-forming reactions of 2-chloro-4,6-dimethoxy-1,3,5-triazine has been reported.[3] Procedure for the preparation of multikilogram quantities of 2-chloro-4,6-dimethoxy-1,3,5-triazine has been reported.[4]

Application

2-Chloro-4,6-dimethoxy-1,3,5-triazine may be used in the following studies:
  • The specific labeling of streptavidin by the modular method for affinity labeling (MoAL).[5]
  • The preparation of bis(4,6-dimethoxy-1,3,5-triazin-2-yl) ether, via reaction with 2-hydroxy-4,6-dimethoxy-1,3,5-triazine.[6]
  • The preparation of 2-(4,6-dimethoxy-1,3,5-triazinyl)trialkylammonium salts, via reaction with various tertiary amines.[7]
  • The synthesis of 4-(4,6-dimethoxy-1,3,5-triazin-2-yl)-4-methylmorpholinium chloride, via coupling with N-methylmorpholine in THF.[8]
A stable, yet highly reactive, peptide coupling agent.[1]

The reaction of 2-chloro-4,6-dimethoxy-1,3,5-triazine (CDMT) with various nitrogen-containing compounds, particularly tertiary amines (tert-amines), has been studied for the preparation of 2-(4,6-dimethoxy-1,3,5-triazinyl)trialkylammonium salts [DMT-Am(s)]. DMT-Ams derived from aliphatic tert-amines exhibited activity for the dehydrocondensation between a carboxylic acid and an amine

We studied the specific labeling of streptavidin using the modular method for affinity labeling (MoAL) that we developed based on a catalytic amide-forming reaction using 2-chloro-4,6-dimethoxy-1,3,5-triazine (CDMT) and a tertiary amine catalyst. The primary structures of avidin and streptavidin are

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.
