Description

App+ CAS NO 1141-41-9 is a high-purity chemical intermediate, also known as 2,2,6,6-Tetramethyl-4-piperidinol, valued for its role as a key precursor in the synthesis of hindered amine light stabilizers (HALS). This compound is critical for enhancing the durability and longevity of polymers by effectively scavenging free radicals generated by UV exposure. It is primarily sought after by manufacturers in the plastics, coatings, and specialty chemical industries for producing advanced stabilizer formulations.

Application

• Hindered Amine Light Stabilizer (HALS) Synthesis: Serves as the fundamental building block for manufacturing high-performance light stabilizers used in polyolefins, engineering plastics, and automotive coatings.
• Polymer Additives: Incorporated into additive packages to prevent photo-degradation, color fading, and loss of mechanical properties in plastics exposed to outdoor environments.
• Advanced Coating Systems: Used in the formulation of UV-resistant clear coats, industrial paints, and wood coatings to ensure long-term gloss retention and surface protection.
• Agrochemical Formulations: Acts as an intermediate in the synthesis of certain agrochemicals that require a stabilized piperidine structure.
• Pharmaceutical Research: Utilized as a synthetic intermediate in the development of novel pharmaceutical compounds and bioactive molecules.
• Specialty Chemical Manufacturing: Employed in organic synthesis for creating complex molecules where a sterically hindered amine functionality is required.

Quality Control

Our App+ CAS NO 1141-41-9 is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for sensitive synthesis applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and consistency for our global B2B clients.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product quality.
