o-Phthalaldehyde-Diluent

Overview

Bottle of o-Phthalaldehyde (opa ) Diluento-Phthalaldehyde (opa ) Diluent

Chromatographic Grade™ for Preparation of o-Phthalaldehyde Reagents

The derivatization of primary amines with o-Phthalaldehyde and a mercaptan requires basic conditions. To ensure the optimum pH of the reaction it is important to use the correct diluent.

Three application specific diluents are available : CB910 and GA104 for Carbamate and Glyphosate analyses respectively, and OD104 for analysis of amino acids and other amines.

These borate buffers are produced from starting materials which are free of heavy metals and amines. As with most other products of Pickering Laboratories, the quality of the OPA Diluents is verified by actual post-column HPLC analysis.

o-phthalaldehyde

Overview

Bottle of o-phthalaldehydeo-phthalaldehyde (opa )

Chromatographic Grade™ For Automated 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.
