Description
Product Description: o-Phthalaldehyde Chromatographic Grade (OPA )
o-Phthalaldehyde Chromatographic Grade (OPA) is for Post-column Derivatization of Primary Amines.
Primary amines form highly fluorescent adducts when reacted with o-Phthalaldehyde (OPA) and a mercaptan under basic conditions.
The products of this reaction, 1-alkyl-2-thioalkyl-substituted isoindoles, exhibit optimal excitation at 330 nm and maximal emission at 465 nm.
Pickering’s OPA is specially prepared to meet the demanding requirements of high-sensitivity pre- and post-column HPLC derivatization methods. Our repurification process actually begins with commercially available 99 % material.
The entire process is controlled to eliminate trace interfering contamination. Lot quality is verified by post-column HPLC using a high-sensitivity fluorescence detector.
o-Phthalaldehyde Chromatographic Grade (OPA) is KayDee Tek part number is: KDT-O120-N and it comes in a bottle of 5 grams.
KayDee Tek also carries these other reagents for post column methods.
