2 β,7-Dihydroxy-1-methyl-8-methylene-4b β-gibb-4-ene-1α,10 β-dicarboxylic Acid CAS 19123-84-3

Description

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.

2 β,7-Dihydroxy-1-methyl-8-methylene-4b β-gibb-4-ene-1α,10 β-dicarboxylic Acid (CAS 19123-84-3) is a high-purity analytical reference standard with the molecular formula C19H24O6 and a molecular weight of 348.39 g/mol.

The molecular framework of 2 β,7-Dihydroxy-1-methyl-8-methylene-4b β-gibb-4-ene-1α,10 β-dicarboxylic Acid (C19H24O6) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
