Product Description
O-Phthalaldehyde (OPA, CAS No. 643-79-8) is a refined aromatic aldehyde supplied in pale yellow crystalline form, designed for use in chemical synthesis and fine chemical manufacturing. The product is manufactured under controlled conditions to ensure high purity, consistent quality, and reliable performance in downstream applications. With a minimum purity of 99.0%, it meets the requirements of customers seeking stable and reproducible chemical intermediates.
This OPA product demonstrates a well-defined melting point range, which supports ease of handling during storage and processing. The tightly controlled moisture level significantly minimizes the potential for undesired reactions, helping to improve overall reaction efficiency and product yield. These characteristics make it suitable for a wide range of professional and industrial applications, including pharmaceutical intermediates and specialty chemical formulations.
Quality control is implemented throughout the entire production process, from raw material selection to final inspection. Each batch undergoes comprehensive testing and is accompanied by a Certificate of Analysis (COA) to ensure full traceability and compliance with agreed specifications. The uniform crystalline appearance reflects stable physical properties and consistent production standards.
The product is packaged to maintain integrity during transportation and long-term storage. When kept in a dry, cool, and well-ventilated environment, it retains its quality and performance over its intended shelf life. Packaging formats can be customized according to customer requirements to support safe shipment and efficient handling.
