3-Pentanone, 2,4-dimethyl-, semicarbazone is a chemical compound with the molecular formula C8H17NO2. It is derived from 3-pentanone, a ketone with a five-carbon chain, by substituting two hydrogen atoms with methyl groups at the 2nd and 4th positions, resulting in a 2,4-dimethyl-3-pentanone structure. The semicarbazone derivative is formed by reacting this ketone with semicarbazide, a derivative of hydrazine, to form a semicarbazone adduct. 3-Pentanone, 2,4-dimethyl-, semicarbazone is often used in organic synthesis and as an analytical reagent. It is characterized by its ability to form a stable complex with carbonyl compounds, which can be useful in various chemical analyses and reactions. The compound is typically a white crystalline solid and is sensitive to moisture, requiring storage under dry conditions.

5338-14-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5338-14-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,3,3 and 8 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 5338-14:
(6*5)+(5*3)+(4*3)+(3*8)+(2*1)+(1*4)=87
87 % 10 = 7
So 5338-14-7 is a valid CAS Registry Number.

Reactions of diazoalkanes with isocyanates. Synthesis of imidazolidine-2,4-diones, oxindoles, and oxazolidinones

Fulton, Janet B.,Warkentin, John

, p. 1177 - 1184 (2007/10/02)

Thermolysis of a 5,5-dialkyl-Δ3-1,3,4-oxadiazolin-2-one in nitrobenzene containing an aryl isocyanate at 150 deg C affords a 1,3-diaryl-5,5-dialkyl imidazolidine-2,4-dione, an N-arylcarbamoyl-3,3-dialkyloxindole, and a 3-aryl-2-arylimino-5,5-dialkyl-1,3-oxazolidin-4-one.Those products arise from attack of a diazoalkane, generated in situ from the oxadiazolinone by thermal cycloreversion, on the isocyanate function.Two imidazolidine diones, three oxazolidinones, and 14 oxindoles were prepared.
