What is O-Phthalaldehyde used for?
What is O-Phthalaldehyde used for?
Ortho-Phthalaldehyde (OPA) has been approved for high-level sterilization of heat-sensitive medical instruments and is increasingly being used as a replacement in the healthcare industry for glutaraldehyde, a known sensitizer.
What is the unique characteristic of an ortho-Phthalaldehyde?
OPA has several potential advantages compared with glutaraldehyde. It has excellent stability over a wide pH range (pH 3 to 9), is not a known irritant to the eyes and nasal passages, does not require exposure monitoring, has a barely perceptible odor, and requires no activation.
What is Fluoraldehyde?
Fluoraldehyde Reagent Solution contains OPA (o-phthalaldehyde), which reacts with primary amines of amino acids, peptide and proteins to enable fluorescent detection and quantitation. The Fluoraldehyde Reagent Solution is supplied ready to use and enables fast quantitation of proteins or peptides in solution.

Phthalaldehyde (sometimes also o-phthalaldehyde or ortho-phthalaldehyde, OPA) is the chemical compound with the formula C6H4(CHO)2. It is one of three isomers of benzene dicarbaldehyde, related to phthalic acid.
What is Iupac name of Phthalaldehyde?
What is OPA assay?
A rapid and convenient spectrophotometric assay has been devised to measure proteolysis. The assay is based on the reaction of o-phthalaldehyde (OPA) and 2-mercaptoethanol with amino groups released during proteolysis of a protein substrate.
How is OPA reagent prepared?
The OPA reagent is prepared by mixing (a) 99 ml of 3% (w/v) boric acid in water (pH adjusted to 10.5 with KOH), (b) 1 ml of ethanol containing 50 mg of OPA, and (c) 50 μ1 of 2-mercaptoethanol. The OPA reagent is stable for approximately 1 week when stored in the refrigerator.
