Dibenzothiophene (DBT, diphenylene sulfide) is the organosulfur compound consisting of two benzene rings fused to a central thiophene ring. It has the chemical formula C 12 H 8 S. It is a colourless solid that is chemically somewhat similar to anthracene .
Dibenzofuran is a relatively non-toxic compound as evidenced by rats being unaffected after a 200-day diet consisting of 0.025 – 0.4% of DBF. [1] The polychlorinated dibenzofurans are however among the potentially toxic dioxins and dioxin-like compounds.
If the reaction mixture is not anhydrous, this minor reaction pathway is suppressed as water acts as a competing base. [12] Oxidation of thiophenes may be relevant to the metabolic activation of various thiophene-containing drugs, such as tienilic acid and the investigational anticancer drug OSI-930. [16] [17] [18] [19]
Dithiobenzoic acid is the organosulfur compound with the formula C 6 H 5 CS 2 H. It is a dithiocarboxylic acid , an analogue of benzoic acid , but more acidic and deeply colored. Synthesis and reactions
3,5-Dinitrobenzoyl chloride (C 7 H 3 ClN 2 O 5) is an organic compound with a melting point of 68–69 °C. [1] It is the acyl chloride of 3,5-dinitrobenzoic acid and like it is mainly used in the analysis of organic substances by derivatization .
Benzoic acid is a constituent of Whitfield's ointment which is used for the treatment of fungal skin diseases such as ringworm and athlete's foot. [ 28 ] [ 29 ] As the principal component of gum benzoin , benzoic acid is also a major ingredient in both tincture of benzoin and Friar's balsam.
Acetoacetic acid (IUPAC name: 3-oxobutanoic acid, also known as acetonecarboxylic acid or diacetic acid) is the organic compound with the formula CH 3 COCH 2 COOH. It is the simplest beta- keto acid , and like other members of this class, it is unstable.
Melting point: −78 °C; −109 °F; ... It is formed in an esterification reaction of sec-amyl alcohol (2-pentanol) and acetic acid. [2]
