General description

Crystals of 3,5-dinitrobenzoyl chloride (DNBC) belong to the orthorhombic crystal system and space group Pna21.[1] It is widely used reagent for the detection of alcohols.[2]

Application

3,5-Dinitrobenzoyl chloride may be used for the quantitative estimation of hydroxyl groups in pyridine.[2] It may be used in the synthesis of following:
  • 3,5-diamino-N-cyclopropylbenzamide[3]
  • 3,5-dinitro-N-cyclopropylbenzamide[3]
  • 4-(3,5-dinitrophenyl)-6-(dipropan-2-ylamino)-2H-1,3,5-thiadiazine-2-thione4


3,5-Dinitrobenzoyl chloride may also be used as derivatizing agent for the following:

  • biogenic amines present in fermented foods, which can be determined using liquid chromatography method(LC)[4]
  • polyamines, present in biological fluids, which can be determined using high performance liquid chromatography(HPLC)[5]

A carbocyclic analogue of distamycin was obtained, in which the N-methylpyrrole rings were substituted by disubstituted benzene rings. Additionally, N-chloro- or N-bromoacetyl groups, displaying alkylating properties, were introduced. The synthesis, starting from 3,5-dinitrobenzoyl chloride, consisted of five stages.

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.
      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
