Description

Propionaldehyde (also known as propanal) is a versatile and essential C3 aldehyde intermediate in organic synthesis. Its high reactivity, particularly as an electrophile, makes it a crucial building block for producing a wide range of downstream chemicals. This product is indispensable for manufacturers in the pharmaceutical, agrochemical, flavor & fragrance, and polymer industries seeking reliable, high-purity raw materials for their processes.

Application

• Chemical Synthesis Intermediate: Primary use in the production of n-propanol, propionic acid, and trimethylolethane (TME).
• Pharmaceutical Manufacturing: Key starting material (KSM) or intermediate in the synthesis of various active pharmaceutical ingredients (APIs).
• Agrochemical Production: Used in the manufacture of herbicides, pesticides, and plant growth regulators.
• Flavor & Fragrance Industry: Employed in the synthesis of aroma chemicals and flavoring agents.
• Polymer & Resin Modifier: Serves as a cross-linking agent and modifier in certain plastic and resin formulations.
• Rubber Chemicals: Used in the production of vulcanization accelerators and antioxidants.

Quality Control

Our Propionaldehyde is manufactured under a strict quality management system to ensure batch-to-batch consistency and high purity. Quality is verified through comprehensive analytical testing including gas chromatography (GC). A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flame. Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) and keep containers tightly sealed when not in use. Keep away from strong oxidizing agents, strong bases, and reducing agents.
