Description

2-Chloro-4-Fluoro-5-Nitrophenyl Ethyl Carbonate is a high-purity, multi-functional aromatic intermediate of significant importance in advanced organic synthesis. Its core value lies in its unique halogenated and nitrated phenyl carbonate structure, which serves as a versatile building block for constructing complex molecules. This compound is primarily needed by research and development chemists and process engineers in the pharmaceutical, agrochemical, and specialty chemical industries for the development of novel active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly those requiring halogenated aromatic scaffolds.
• Agrochemical Synthesis: Used in the development of advanced herbicides, fungicides, and insecticides where the nitrophenyl group is a critical functional moiety.
• Organic Synthesis Building Block: Serves as a protected phenol derivative or a reactive electrophile in multi-step synthesis for complex organic molecules.
• Material Science Research: Employed in the creation of specialty polymers, liquid crystals, or advanced organic electronic materials.
• Chemical Research & Development: A valuable reagent for method development and exploring new reaction pathways in academic and industrial R&D labs.
• Dye and Pigment Intermediate: Potential use in the synthesis of specialized colorants and pigments due to its nitro-aromatic structure.

Quality Control

Our 2-Chloro-4-Fluoro-5-Nitrophenyl Ethyl Carbonate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, GC, NMR, and IR spectroscopy, to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all critical quality parameters. Our commitment is to supply material that meets the stringent requirements for research and cGMP-grade pharmaceutical intermediate applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (typically 15-25°C). This material is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed and away from direct light sources to maintain stability and purity.
