Description

Propionyl Bromide is a versatile and highly reactive organic acid halide used as a key building block in chemical synthesis. Its primary value lies in its ability to efficiently introduce the propionyl group into target molecules, making it essential for creating complex intermediates. This compound is particularly valuable for manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries seeking to develop active ingredients, fine chemicals, and functional materials.

Application

• Pharmaceutical Intermediates: A crucial reagent for the synthesis of active pharmaceutical ingredients (APIs), particularly in the production of propionate-based drugs and other bioactive molecules.
• Agrochemical Synthesis: Used in the manufacturing of herbicides, fungicides, and plant growth regulators where the propionyl moiety is a key functional group.
• Fine Chemical Production: Serves as a fundamental acylating agent in organic synthesis for creating esters, amides, and ketones in research and industrial-scale processes.
• Polymer Chemistry: Employed as a modifier or chain initiator in the production of specialized polymers and resins to alter material properties.
• Dye and Pigment Manufacturing: Acts as an intermediate in the synthesis of complex organic dyes and colorants.
• Laboratory Research: A valuable tool for academic and industrial R&D in medicinal chemistry and material science for structure-activity relationship (SAR) studies.

Quality Control

Our Propionyl Bromide is manufactured under stringent quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including assay, identity confirmation, and impurity profiling. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting compliance with agreed specifications. We support our global B2B clients with the documentation required for their regulatory and quality assurance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and incompatible materials. Due to its hygroscopic and highly volatile nature, containers should be kept tightly sealed under an inert atmosphere (e.g., nitrogen) to maintain purity and prevent decomposition. Recommended storage temperature is 2-8°C for long-term stability.
