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.
Methyl Octadecanoate-d35 (CAS 29823-25-4) is a high-purity analytical reference standard with the molecular formula C19H3D35O2 and a molecular weight of 333.72 g/mol.
Owing to deuterium isotope labeling, a steroid core, a hydroxyl group, an ether linkage, Methyl Octadecanoate-d35 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 333.72 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
