O phthalaldehyde opa
Manufactured by Sinopharm
Sourced in China
O-phthalaldehyde (OPA) is a chemical compound used as a laboratory reagent. It is a colorless to pale yellow liquid with a pungent odor. OPA is primarily utilized as a fluorogenic derivatizing agent in high-performance liquid chromatography (HPLC) analysis for the detection and quantification of primary and secondary amines.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
