Ortho-Phthalaldehyde (OPA) Disinfectant Grade, ≥99.0% Purity, Light Yellow Liquid for Medical Use

Ortho-Phthalaldehyde (OPA) is a high-performance aromatic dialdehyde compound widely used in high-level disinfection and chemical synthesis. This product is manufactured to a minimum purity of 99.5% and appears as a pale yellow crystalline solid. Due to its strong and broad-spectrum antimicrobial activity, OPA is frequently used as a high-level disinfectant for reusable medical and surgical instruments, particularly in environments requiring low-odor and low-irritation alternatives to glutaraldehyde.

OPA’s chemical stability, low vapor pressure, and ease of handling make it ideal not only for disinfection applications but also as a valuable intermediate in the production of pharmaceutical compounds, dyes, and specialty chemicals.

Our product is manufactured under strict quality control, featuring low moisture content and a tight melting range to ensure consistency in performance and excellent storage stability.
