Octadecanoic acid, 12-hydroxy-, calcium salt (2:1) CAS 3159-62-4

Description

Compared with other compounds in its class, the molecular weight of 339.55 g/mol gives Octadecanoic acid, 12-hydroxy-, calcium salt (2:1) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Octadecanoic acid, 12-hydroxy-, calcium salt (2:1) (CAS 3159-62-4), molecular formula C18H35O3Ca and molecular weight 339.55 g/mol, is a CATO reference standard with documented purity and traceability.

Octadecanoic acid, 12-hydroxy-, calcium salt (2:1) (C18H35O3Ca) contains a carboxylic acid group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
