Description

2-Pyrrolidinone is a versatile, high-purity heterocyclic organic compound and a key building block in chemical synthesis. Its exceptional solvent properties and reactive lactam structure make it a critical intermediate for producing high-value polymers, pharmaceuticals, and agrochemicals. This product is essential for manufacturers in the pharmaceutical, agrochemical, polymer, and electronics industries seeking reliable, high-quality raw materials for advanced formulations.

Application

• Pharmaceutical Intermediate: A crucial precursor in the synthesis of various active pharmaceutical ingredients (APIs), including nootropic agents like Piracetam and other pyrrolidone derivatives.
• Polymer Industry: Serves as a monomer and solvent for producing specialty polymers like polyvinylpyrrolidone (PVP), which is used in adhesives, coatings, and personal care products.
• Agrochemical Synthesis: Used in the manufacture of pesticides, herbicides, and plant growth regulators due to its reactive nitrogen-containing ring.
• Electronics & Specialty Chemicals: Employed as a high-purity solvent and processing aid in photoresist formulations, lithium-ion battery electrolytes, and other electronic chemicals.
• Chemical Synthesis Solvent: Acts as a powerful, aprotic dipolar solvent for organic reactions, including condensations and polymerizations, where it facilitates high conversions.
• Personal Care & Cosmetics: Used in the production of PVP and other ingredients for hair sprays, shampoos, and skin care products as a film-forming agent and stabilizer.

Quality Control

Our 2-Pyrrolidinone is manufactured under a strict quality management system to ensure batch-to-batch consistency and high purity. We provide comprehensive quality assurance, with products typically meeting specifications for pharmaceutical and technical grades. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is available for every batch upon request, supporting your regulatory and quality documentation needs.

Storage

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