1-Bromo-2 4-difluorobenzene / 2 4-Difluorobromobenzene CAS 348-57-2

1. Serves 1-Bromo-2 4-difluorobenzene as a critical intermediate for synthesizing antifungal pharmaceuticals like fluconazole with broad - spectrum and low - toxicity effects.
2. Acts as a core building block for manufacturing selective agrochemicals to improve insecticidal and herbicidal activities in crop protection.
3. Functions 2 4-Difluorobromobenzene CAS 348-57-2 as a reactive reagent for Suzuki - Miyaura cross - coupling reactions in fine organic synthesis and fluorinated material preparation.
4. Serves as a precursor for producing specialty fluorinated materials such as liquid crystal components and organic electronic materials.

1. Store in sealed amber glass containers at 15–25℃ in a cool, dry and well - ventilated warehouse away from direct sunlight.
2. Keep 1-Bromo-2 4-difluorobenzene separated from heat sources, open flames and oxidizing agents to prevent fire and decomposition risks.
3. Wear nitrile gloves, chemical safety goggles and a half - face vapor respirator when loading, unloading and transferring the chemical.
4. Avoid 2 4-Difluorobromobenzene CAS 348-57-2 mixing with strong acids and bases; entrust waste disposal to qualified hazardous chemical treatment institutions.

1. 2,4 - difluoro substitution enhances the metabolic stability and bioavailability of target pharmaceutical and agrochemical products.
2. Reactive bromine group enables efficient carbon - carbon bond formation for diverse molecular modification and derivatization.
3. Has 1-Bromo-2 4-difluorobenzene good solubility in organic solvents like toluene and dichloromethane, adapting to various organic reaction systems.
4. Provides 2 4-Difluorobromobenzene CAS 348-57-2 high chemical purity and stable reactivity, suitable for both laboratory - scale research and industrial - scale production.

1-Bromo-2 4-difluorobenzene is a Class 3 flammable liquid (UN 1993, Packing Group III) with flammable liquid and vapor (H226). It causes skin irritation (H315), serious eye irritation (H319) and respiratory tract irritation (H335) upon contact or inhalation. 2 4-Difluorobromobenzene CAS 348-57-2 is incompatible with strong acids, bases and oxidants; improper mixing may lead to decomposition and release of toxic hydrogen fluoride fumes. Prolonged skin contact can cause chemical burns, and high - concentration inhalation may result in respiratory discomfort.
