Description

Atrp Initiator CAS NO 42069-15-8 is a specialized organobromine compound widely recognized as a highly efficient initiator for Atom Transfer Radical Polymerization (ATRP). This advanced polymerization technique enables precise control over polymer architecture, molecular weight, and polydispersity, which is critical for developing high-performance materials. It is an essential reagent for R&D scientists and production engineers in the polymer, specialty chemical, and advanced materials sectors seeking to create tailored polymers with specific properties.

Application

• Primary initiator for controlled/living radical polymerization via the ATRP mechanism.
• Synthesis of well-defined block copolymers, star polymers, and graft copolymers with narrow molecular weight distributions.
• Manufacture of advanced polymeric materials for coatings, adhesives, and sealants with enhanced performance.
• Production of functional polymers for biomedical applications, including drug delivery systems and hydrogel matrices.
• Research and development of novel polymer architectures in academic and industrial laboratories.
• Fabrication of polymers with specific end-group functionality for further chemical modification.

Quality Control

Our Atrp Initiator is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity, which is critical for achieving predictable polymerization kinetics. Each lot undergoes comprehensive analytical testing, including assay and impurity profile determination. A Certificate of Analysis (COA) detailing purity, identity, and other key parameters is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place. Due to its highly volatile nature, keep the container tightly sealed when not in use and store at temperatures between 2°C and 8°C (refrigerated) for long-term stability. Allow the container to reach room temperature before opening to minimize moisture ingress.
