(-)-Gomisin L1 CAS 82425-43-2

Description

Compared with other compounds in its class, the molecular weight of 386.44 g/mol gives (-)-Gomisin L1 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(-)-Gomisin L1 (CAS 82425-43-2) is a high-purity analytical reference standard with the molecular formula C22H26O6 and a molecular weight of 386.44 g/mol.

The molecular framework of (-)-Gomisin L1 (C22H26O6) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
