WebAn optical parametric amplifier, abbreviated OPA, is a laser light source that emits light of variable wavelengths by an optical parametric amplification process. It is essentially the same as an optical parametric oscillator, but without the optical cavity (i.e., the light beams pass through the apparatus just once or twice, rather than many ...

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. This pale yellow solid is a building block in the synthesis of heterocyclic compounds and a … Ver mais The compound was first described in 1887 when it was prepared from α,α,α’,α’-tetrachloro-o-xylene. A more modern synthesis is similar: the hydrolysis of the related tetrabromo-o-xylene using potassium Ver mais OPA is used in a very sensitive fluorogenic reagent for assaying amines or sulfhydryls in solution, notably contained in proteins, peptides, and amino acids, by capillary electrophoresis Ver mais OPA can be polymerized. In the polymer, one of the oxygen atoms forms a bridge to the other non-ring carbon of the same phthalaldehyde unit, … Ver mais • isophthalaldehyde (benzene-1,3-dicarbaldehyde) • terephthalaldehyde (benzene-1,4-dicarbaldehyde) Ver mais OPA is commonly used as a high-level disinfectant for medical instruments, commonly sold under the brand names of Cidex OPA or TD-8.
