2,4-Pentanedione (CAS NO.123-54-6) is used as pharmaceutical raw materials and organic intermediates, but also can be used for solvents, analytical reagents, tungsten and molybdenum in aluminum extraction agent.
2,4-Pentanedione is made industrially by the thermal rearrangement of isopropenylacetate.
CH2(CH3)COC(O)Me → MeC(O)CH2C(O)Me
Laboratory routes to 2,4-Pentanedione begin also with acetone. Acetone and acetic anhydride upon the addition of BF3 catalyst.
(CH3CO)2O + CH3C(O)CH3 → CH3C(O)CH2C(O)CH3

2,4-Pentanedione (CAS NO.123-54-6) is also named as 2,4-Dioxopentane ; 2,4-Pentadione ; 2-Propanone, acetyl- ; 4-01-00-03662 (Beilstein Handbook Reference) ; ACAC ; AI3-02266 ; Acetoacetone ; Acetone, acetyl- ; Acetyl 2-propanone ; Acetyl acetone ; Acetylacetone ; BRN 0741937 ; CCRIS 3466 ; Diacetylmethane ; HSDB 2064 ; NSC 5575 ; Pentan-2,4-dione ; Pentanedione ; Pentanedione-2,4 . 2,4-Pentanedione (CAS NO.123-54-6) is colorless or yellow colored liquid. It is soluble in water and flammable. 2,4-Pentanedione (CAS NO.123-54-6) is a kind of ketones which are reactive with many acids and bases liberating heat and flammable gases (e.g., H2). The amount of heat may be sufficient to start a fire in the unreacted portion of the ketone. Ketones react with reducing agents such as hydrides, alkali metals, and nitrides to produce flammable gas (H2) and heat. Ketones are incompatible with isocyanates, aldehydes, cyanides, peroxides, and anhydrides. They react violently with aldehydes, HNO3, HNO3 + H2O2, and HClO4. It may dissolve plastics. Inhalation causes dizziness, headache, nausea, vomiting and loss of consciousness. Contact with liquid irritates eyes. Vapor may travel to a source of ignition and flash back.
