描述

一般說明

2-Picoline is a flavor and fragrance standard used for the quality control of food and cosmetic products. It is an isomer of methylpyridine and also a volatile flavor compound reportedly identified in dark chocolates, roasted sesame seed oil, wild rice (Zizania palustris L.), etc.

應用

2-Picoline may be used as an analytical reference standard for the quantification of the analyte in the following:

• Cigarette smoke using reversed-phase high-performance liquid chromatography–electrospray ionization tandem mass spectrometric method (RP-HPLC–ESI-MS/MS).
• Chinese faint-scent cigarettes using gas chromatography–mass spectrometry (GC–MS) technique.

Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
