Propyl bromide

1-Bromopropane_106-94-5_High Purity n-Propylating Agent_Pharmaceutical and Pesticide Intermediate

Core Product Parameters:

1-Bromopropane, also known as n-propyl bromide, CAS registration number 106-94-5, molecular formula C₃H₇Br, molecular weight 123.00. It is a colorless transparent liquid and an important short-chain brominated alkane. Due to its moderate chain length and excellent reactivity, it is widely used as an efficient n-propylating agent, reliably introducing the n-propyl group into molecules, making it a key building block in the synthesis of various high-value-added fine chemicals.

Specifications and Quality Control:

We provide high-purity 1-bromopropane products, with standard specifications ≥99.0% and pharmaceutical grade ≥99.5%. Through advanced distillation processes and strict quality control, our products feature low moisture content (e.g., ≤0.03%), low acid value, and low impurity levels, ensuring excellent efficiency and purity for your critical reactions such as Grignard reactions and nucleophilic substitutions. Batch stability meets the requirements from laboratory R&D to industrial production.

Main Application Areas:

1-Bromopropane is a versatile and important chemical intermediate, with its main applications including:

Pharmaceutical and Pesticide Synthesis: As a key intermediate, it is used in the synthesis of a range of antifungal drugs, cardiovascular medications, and highly effective, low-toxicity pesticides.

Fine Chemicals and Materials: Used in the production of dyes, fragrances, surfactants, and as initiators or modifiers in polymerization reactions.

Organic Synthesis and Research Reagents: Commonly used as a raw material in the preparation of Grignard reagents and propylation reactions, widely applied in research institutions and corporate R&D centers.

Usage, Storage, and Safety Guidelines:

This product is recommended for use in well-ventilated environments and should be kept away from strong oxidizing agents. Store sealed, protected from light, and in a cool, dry place.
