Ortho Phthalaldehyde. CAS No: 643-79-8

Ortho Phthalaldehyde (OPA), with the CAS number 643-79-8, is a chemical compound with the formula C6H4(CHO)2. It is a pale yellow solid, soluble in water at pH < 11.5, and used in various applications including pre-column derivatization of amino acids for HPLC and as a high-level disinfectant. Ortho-phthalaldehyde (OPA) is a highly reactive aromatic dialdehyde widely used as a high-level disinfectant for medical and dental instruments, and as a biochemical reagent. It acts rapidly against bacteria, viruses, and fungi, and is an effective, odorless alternative to glutaraldehyde. Primary UsesHigh-Level Disinfection: Commonly used in healthcare facilities (like endoscopy units) to reprocess heat-sensitive medical devices. It provides effective, room-temperature disinfection in as little as 5 to 12 minutes. Analytical Chemistry: Serves as a vital reagent for pre-column derivatization in amino acid analysis (e.g., via HPLC or GC) and fluorescent labeling. Chemical Synthesis: Used as a building block for synthesizing heterocyclic compounds and specialty chemical formulations Packing : 25 kg
