Butanedial, also known as methoxybutanal or 4-methoxybutanal, is an organic compound with the chemical formula C5H10O2. It is a colorless liquid with a pungent odor and is used as a chemical intermediate in the synthesis of various pharmaceuticals, agrochemicals, and other organic compounds. Butanedial is produced through the reaction of butyraldehyde with methanol in the presence of an acid catalyst. It is a versatile building block in organic synthesis, allowing for the formation of various functional groups and complex molecules. Due to its reactivity, it is important to handle butanedial with care, as it can be harmful if inhaled, ingested, or absorbed through the skin.

5281-75-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5281-75-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,8 and 1 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 5281-75:
(6*5)+(5*2)+(4*8)+(3*1)+(2*7)+(1*5)=94
94 % 10 = 4
So 5281-75-4 is a valid CAS Registry Number.

Syntheses of (-)-pelletierine and (-)-homopipecolic acid

Chiou, Wen-Hua,Chen, Guei-Tang,Kao, Chien-Lun,Gao, Yu-Kai

, p. 2518 - 2520 (2012)

Enantiomeric syntheses of (-)-homopipecolic acid and (-)-pelletierine have been achieved by chiral resolution of tropanol followed by Baeyer-Villiger oxidation. The methodology provides a practical route for the synthesis of optically pure piperidines. The Royal Society of Chemistry 2012.
