Chemical Structure

Ammonium stearate CAS 1002-89-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 301.51 g/mol gives Ammonium stearate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Ammonium stearate (CAS 1002-89-7), molecular formula C18H35O2H4N and molecular weight 301.51 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C18H35O2H4N, Ammonium stearate contains an amide 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 301.51 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.
