n-Eicosanyl-d41 Alcohol CAS 349553-89-5 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

n-Eicosanyl-d41 Alcohol (CAS 349553-89-5), molecular formula C20HD41O and molecular weight 339.80 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C20HD41O, n-Eicosanyl-d41 Alcohol contains deuterium isotope labeling, a steroid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 339.80 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
