Description
BUTOPYRONOXYL, also known as Indalon, is a yellow to pale reddish-brown liquid with an aromatic odor. It is reasonably stable in air and slowly affected by light. This chemical compound is insoluble in water but miscible with alcohol, chloroform, ether, and glacial acetic acid.
Uses
Used in Insect Repellent Industry:
BUTOPYRONOXYL is used as an insect repellent for providing protection against insects when applied directly on the skin. Its effectiveness in repelling insects makes it a valuable component in the development of insect repellent products.
Used in Chemical Industry:
BUTOPYRONOXYL, due to its chemical properties, can be utilized in various applications within the chemical industry. Its miscibility with different solvents allows for its use in the formulation of various products, such as paints, coatings, and adhesives. Additionally, its stability in air and resistance to light exposure make it suitable for use in applications where long-lasting performance is required.
Synthesis
To a 25-mL flflame-dried flflask under a nitrogen atmosphere were added freshly distilled Rawal’s diene (227 mg, 1 mmol, 1.0 equivalents) and 2 mL of CHCl3. Benzaldehyde (1.5 mmol, 1.5 equivalents) was added dropwise via a gas-tight syringe. The reaction mixture was stirred at room temperature for 2 h and then diluted with 15 mL of CH2Cl2. The yellow solution was cooled to ?78 °C and treated with 142 μL acetyl chloride (2 mmol, 2 equivalents). After stirring for about 30 min, saturated Na2CO3 was added. The organic layer was separated and the water phase was diluted with 15 mL of water and extracted twice with CH2Cl2. The combined organic phase was dried with MgSO4, fifiltered, and concentrated to give a yellow oil, which was subjected to flflash chromatography to afford the desired dihydropyrone in 86% overall yield.

flame. When heated to decomposition it
emits acrid fumes.
Check Digit Verification of cas no
The CAS Registry Mumber 532-34-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,3 and 2 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 532-34:
(5*5)+(4*3)+(3*2)+(2*3)+(1*4)=53
53 % 10 = 3
So 532-34-3 is a valid CAS Registry Number.
