Description

2-Oxobutanaldehyde is a versatile and reactive α-keto aldehyde compound, serving as a critical building block in advanced organic synthesis. Its bifunctional nature, featuring both a ketone and an aldehyde group, makes it a valuable precursor for constructing complex heterocyclic structures and fine chemicals. This high-purity intermediate is essential for research and production in the pharmaceutical, agrochemical, and specialty chemical industries, where precise molecular architecture is required.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of various active pharmaceutical ingredients (APIs), particularly those containing heterocyclic cores like imidazoles and pyrazines.
• Agrochemical Synthesis: Used in the manufacture of advanced herbicides, fungicides, and plant growth regulators, leveraging its reactivity to form specific bioactive motifs.
• Flavor & Fragrance Industry: Acts as a starting material for creating complex aroma chemicals and flavoring agents due to its reactive carbonyl groups.
• Chemical Research & Development: A fundamental reagent in academic and industrial R&D for exploring new organic reactions and synthesizing novel molecular libraries.
• Specialty Polymer Crosslinker: Utilized in the production of specialty resins and polymers where its dual functionality can introduce cross-linking points.
• Fine Chemical Production: Employed in the multi-step synthesis of complex dyes, pigments, and other performance chemicals.

Quality Control

Our 2-Oxobutanaldehyde is manufactured under stringent quality management systems to ensure batch-to-batch consistency and high purity. Each lot is subjected to comprehensive analytical testing, including chromatography and spectroscopy, to verify identity, potency, and impurity profiles. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment. We adhere to cGMP principles where applicable, supporting our commitment to supply reliability for critical B2B applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its properties of being easily oxidized (store under inert atmosphere) and highly volatile, it is recommended to keep the container under an inert gas blanket after opening and to minimize headspace. Keep away from heat, sparks, and open flame.
