Description

2-Oxazolecarboxaldehyde, 5-(1,1-Dimethylethyl)- (9Ci) is a specialized heterocyclic aldehyde building block of significant interest in advanced organic synthesis. Its core value lies in the reactive aldehyde group and the sterically hindered tert-butyl substituent on the oxazole ring, which enables the construction of complex molecular architectures. This high-purity intermediate is primarily needed by research institutions and pharmaceutical companies engaged in the development of novel active pharmaceutical ingredients (APIs), agrochemicals, and functional materials.

Application

• Pharmaceutical Intermediate: A key synthon for the synthesis of novel drug candidates, particularly in medicinal chemistry programs targeting heterocyclic scaffolds.
• Agrochemical Research: Used in the development of new pesticides and herbicides, where the oxazole moiety can contribute to biological activity.
• Ligand and Catalyst Synthesis: Serves as a precursor for creating specialized ligands used in asymmetric catalysis and metal-organic frameworks (MOFs).
• Material Science: Employed in the research and development of organic electronic materials, such as OLEDs and conductive polymers.
• Chemical Biology Probes: Useful for synthesizing labeled compounds or probes for studying biological processes.
• Custom Synthesis & Contract Manufacturing: A critical starting material for custom synthesis houses serving the fine chemical and life science industries.

Quality Control

Every batch of 2-Oxazolecarboxaldehyde, 5-(1,1-Dimethylethyl)- (9Ci) is produced and analyzed under strict quality management protocols to ensure high purity and batch-to-batch consistency. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat, sparks, and open flame.
