Product Name: Factory Supply 2-Iodoxybenzoic acid
CAS Number: 61717-82-6
2-Iodoxybenzoic acid, also known as IBX, is a highly versatile and useful oxidizing agent in organic chemistry. It is a white to off - white crystalline solid. The molecular formula of 2 - Iodoxybenzoic acid is C₇H₅IO₃, and its molecular weight is approximately 280.02 g/mol. It has a melting point in the range of about 230 - 235°C. This product is typically supplied in high - purity form, ensuring its effectiveness in various chemical reactions.
2 - Iodoxybenzoic acid is widely used in organic synthesis. One of its primary applications is as an oxidizing agent. It can oxidize a variety of functional groups, such as alcohols to aldehydes or ketones under mild conditions. This makes it an important reagent in the synthesis of pharmaceuticals, natural products, and fine chemicals. For example, in the synthesis of complex bioactive molecules, IBX can be used to introduce carbonyl groups selectively, which is crucial for the construction of the desired molecular structures. It can also be used in the oxidation of amines to imines, which are important intermediates in organic synthesis.
When using 2 - Iodoxybenzoic acid, it is essential to follow proper safety procedures. First, ensure that you are working in a well - ventilated area, preferably under a fume hood. Wear appropriate personal protective equipment, such as gloves and goggles.
For a typical oxidation reaction, dissolve the substrate (e.g., alcohol) in a suitable solvent. Common solvents for IBX reactions include DMSO (dimethyl sulfoxide), DCM (dichloromethane), or acetonitrile. Then, add the calculated amount of 2 - Iodoxybenzoic acid to the reaction mixture slowly while stirring. The reaction temperature can vary depending on the substrate and the reaction requirements, but it is often carried out at room temperature or slightly elevated temperatures (up to 50 - 60°C). After the reaction is complete, which can be monitored by TLC (thin - layer chromatography) or other analytical methods, the reaction mixture can be worked up by standard procedures, such as extraction, filtration, and purification.
Case 1: Synthesis of a Pharmaceutical Intermediate
In a pharmaceutical research project, the goal was to synthesize an intermediate for a new anti - cancer drug. The target molecule required the conversion of a primary alcohol to an aldehyde. By using 2 - Iodoxybenzoic acid as the oxidizing agent, the reaction was carried out in DMSO at room temperature. After 3 hours of reaction, the product was obtained with a high yield of 85%. The reaction conditions were mild, which avoided over - oxidation and side - reactions. The resulting aldehyde was then successfully used in the subsequent steps of the synthesis, leading to the production of the desired pharmaceutical intermediate.
Case 2: Total Synthesis of a Natural Product
In the total synthesis of a complex natural product, 2 - Iodoxybenzoic acid was used to oxidize a secondary alcohol to a ketone. The reaction was carried out in acetonitrile at 40°C for 4 hours. The use of IBX allowed for a selective oxidation, while other oxidizing agents might have caused unwanted reactions with other functional groups in the molecule. The ketone product was isolated and further transformed to complete the total synthesis of the natural product.
