15-Mercaptopentadecanoic acid CAS 184639-70-1

Description

Compared with other compounds in its class, the molecular weight of 274.46 g/mol gives 15-Mercaptopentadecanoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

15-Mercaptopentadecanoic acid (CAS 184639-70-1), molecular formula C15H30O2S and molecular weight 274.46 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C15H30O2S, 15-Mercaptopentadecanoic acid contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 274.46 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.

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

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.
