Description

Acetic Acid, Chlorooxo-, Phenylmethyl Ester is a specialized organic ester compound, also known as benzyl chloroacetate. This chemical serves as a versatile and reactive intermediate, valued for its ability to introduce the benzyloxycarbonyl and chloroacetyl functional groups into target molecules. It is primarily sought by research and development laboratories and fine chemical manufacturers engaged in synthetic organic chemistry. Its applications span the development of pharmaceuticals, agrochemicals, and advanced material precursors.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of active pharmaceutical ingredients (APIs), particularly for introducing protective groups or specific molecular fragments.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and plant growth regulators where the chloroacetyl moiety is required.
• Peptide Chemistry: Acts as a reagent for the benzyloxycarbonyl (Cbz) protection of amine groups during peptide synthesis.
• Fine Chemical Production: Employed in the manufacture of dyes, fragrances, and other specialty organic compounds.
• Polymer & Material Science: Serves as a monomer or cross-linking agent in the development of specialty polymers and resins.
• Chemical Research: Utilized in academic and industrial R&D for method development and exploring new synthetic pathways.

Quality Control

Our Acetic Acid, Chlorooxo-, Phenylmethyl Ester is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including assay, identity confirmation, and impurity profiling, to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) documenting purity, physical properties, and safety data are provided with every shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed when not in use to prevent degradation from atmospheric moisture. Keep away from heat, sparks, and open flame.
