Chemical Structure

(4aR,5S,6R,8aS)-5-(2-(furan-3-yl)ethyl)-8a-(hydroxymethyl)-5,6-dimethyl-4a,5,6,7,8,8a-hexahydronaphthalene-1-carboxylic acid CAS 51905-84-1 chemical structure

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.

(4aR,5S,6R,8aS)-5-(2-(furan-3-yl)ethyl)-8a-(hydroxymethyl)-5,6-dimethyl-4a,5,6,7,8,8a-hexahydronaphthalene-1-carboxylic acid (CAS 51905-84-1) is a high-purity analytical reference standard with the molecular formula C20H26O4 and a molecular weight of 330.42 g/mol.

The molecular framework of (4aR,5S,6R,8aS)-5-(2-(furan-3-yl)ethyl)-8a-(hydroxymethyl)-5,6-dimethyl-4a,5,6,7,8,8a-hexahydronaphthalene-1-carboxylic acid (C20H26O4) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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).

As a certified reference material (CRM), (4aR,5S,6R,8aS)-5-(2-(furan-3-yl)ethyl)-8a-(hydroxymethyl)-5,6-dimethyl-4a,5,6,7,8,8a-hexahydronaphthalene-1-carboxylic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
