What is CAS 25629-50-9?

CAS 25629-50-9 refers to a specific chemical entity: 3-(2-Chlorophenyl)-5-methylisoxazole-4-carbonyl Chloride. This compound is an acyl chloride derivative of an isoxazole ring system. The 'CAS' designation, a unique numerical identifier assigned by the Chemical Abstracts Service, ensures unambiguous identification of this specific substance across the globe. Its molecular formula is C11H7Cl2NO2, and it typically presents as a white solid with a high purity, often exceeding 99% when sourced from reputable suppliers.

Key Properties and Reactivity

The defining feature of 3-(2-Chlorophenyl)-5-methylisoxazole-4-carbonyl Chloride is the presence of the carbonyl chloride group. This functional group imparts significant reactivity, making it an excellent electrophile for nucleophilic acyl substitution reactions. This characteristic is precisely why it's so valuable:

  • Acylation: It readily reacts with nucleophiles such as alcohols and amines to form esters and amides, respectively. These reactions are fundamental in building more complex organic structures.
  • Synthetic Intermediate: Its structured functionality makes it a vital intermediate in the multi-step synthesis of pharmaceutical drugs and agrochemicals.
  • Stability: While reactive, it is generally stable under appropriate storage conditions (e.g., cool, dry, inert atmosphere), ensuring its efficacy when you buy and use it.

The isoxazole ring system, along with the chlorophenyl and methyl substituents, further dictates its precise chemical behavior and application potential.

Applications Driven by its Structure

The primary application of CAS 25629-50-9 is as an intermediate in the synthesis of pharmaceuticals. It is a crucial building block for compounds that exhibit pharmacological activity, such as isoxazolyl penicillin derivatives, anticonvulsants, and anti-inflammatory agents. Its specific structure allows for the targeted synthesis of molecules that can interact with biological pathways. Beyond pharmaceuticals, its versatility makes it relevant in the development of certain agrochemicals and as a tool in advanced organic research.
