Description

Benzyl-Carbamic Acid Prop-2-Ynyl Ester CAS NO 119258-49-0 is a specialized organic compound belonging to the carbamate class, characterized by the presence of a benzyl group and a propargyl (prop-2-ynyl) ester moiety. This structure makes it a valuable synthetic intermediate and building block in advanced organic synthesis, particularly for the development of pharmaceuticals and agrochemicals. It is primarily sought by research and development chemists, process development scientists, and manufacturers in the fine chemical and pharmaceutical industries for constructing complex molecular architectures.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of active pharmaceutical ingredients (APIs), especially those requiring carbamate or propargyl functional groups for activity or further derivatization.
• Agrochemical Research: Used in the development of novel pesticides, herbicides, and fungicides where the carbamate moiety can impart specific biological activity.
• Organic Synthesis Reagent: Serves as a versatile reagent for introducing protected amine (carbamate) groups or for participating in click chemistry reactions via its alkyne functionality.
• Material Science Precursor: Potential use in the synthesis of specialized polymers, coatings, or ligands where the benzyl and propargyl groups offer unique chemical handles.
• Bioconjugation & Probe Development: The propargyl group enables efficient conjugation to azide-containing molecules via copper-catalyzed azide-alkyne cycloaddition (CuAAC), useful in creating diagnostic probes or bioconjugates.

Quality Control

Our Benzyl-Carbamic Acid Prop-2-Ynyl Ester is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity, IR and NMR for structural confirmation, and tests for residual solvents and moisture, to ensure it meets high-purity standards suitable for research and synthesis. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, the container should be opaque or stored in dark conditions.
