Chemical Structure

Menaquinone 7 CAS 2124-57-4 chemical structure

Description

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, Menaquinone 7 is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 649.00 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Menaquinone 7 (CAS 2124-57-4) is a high-purity analytical reference standard with the molecular formula C46H64O2 and a molecular weight of 649.00 g/mol.

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.
