Description

Compared with other compounds in its class, the molecular weight of 528.88 g/mol gives 5-(4-(2-[5S-(tert-Butyl-dimethyl-silanyloxy)-2-methylene-cyclohexylidene]-ethylidene)-7R-methyl-octahydro-inden-1R-yl)-(R)-hexanoic acid ethyl ester distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-(4-(2-[5S-(tert-Butyl-dimethyl-silanyloxy)-2-methylene-cyclohexylidene]-ethylidene)-7R-methyl-octahydro-inden-1R-yl)-(R)-hexanoic acid ethyl ester (CAS 147125-14-2) is a high-purity analytical reference standard with the molecular formula C33H56O3Si and a molecular weight of 528.88 g/mol.

Based on its molecular formula C33H56O3Si, 5-(4-(2-[5S-(tert-Butyl-dimethyl-silanyloxy)-2-methylene-cyclohexylidene]-ethylidene)-7R-methyl-octahydro-inden-1R-yl)-(R)-hexanoic acid ethyl ester contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 528.88 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
