Description

7-Heptadecyne, 17-Chloro- is a high-purity, long-chain alkyne derivative featuring a terminal chloro substituent. This unique bifunctional structure makes it a valuable advanced intermediate for organic synthesis, particularly in the construction of complex molecules and functional materials. It is primarily sought by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and specialty chemical industries for applications requiring precise molecular architecture.

Application

• Pharmaceutical Intermediate: Serves as a key building block for the synthesis of novel active pharmaceutical ingredients (APIs), especially in medicinal chemistry research targeting new therapeutic agents.
• Agrochemical Synthesis: Used in the development and production of advanced crop protection agents, including herbicides and fungicides, where its alkyne and chloro groups enable specific functionalization.
• Material Science Research: Acts as a monomer or precursor in polymer chemistry for creating specialty polymers, coatings, or liquid crystals with tailored properties.
• Organic Synthesis Reagent: Employed in cross-coupling reactions (e.g., Sonogashira coupling) and other catalytic transformations to introduce long aliphatic chains with reactive handles.
• Chemical Biology Probes: Utilized in the synthesis of molecular probes and tags for bio-conjugation and labeling studies due to its reactive functional groups.
