General description

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

Application

3,5-Dinitrobenzoyl chloride may be used for the quantitative estimation of hydroxyl groups in pyridine. It may be used in the synthesis of following:
  • 3,5-diamino-N-cyclopropylbenzamide
  • 3,5-dinitro-N-cyclopropylbenzamide
  • 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)
  • polyamines, present in biological fluids, which can be determined using high performance liquid chromatography(HPLC)
