Chemical Structure
Description
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.
Cholesteryl (pyren-1-yl)hexanoate (CAS 96886-70-3) is a high-purity analytical reference standard with the molecular formula C49H64O2 and a molecular weight of 685.03 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, Cholesteryl (pyren-1-yl)hexanoate is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 685.03 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
