Chemical Structure

Zinc(II) (R,Z)-12-hydroxyoctadec-9-enoate CAS 13040-19-2 chemical structure

Description

Zinc(II) (R,Z)-12-hydroxyoctadec-9-enoate (CAS 13040-19-2), molecular formula C18H33O3Zn and molecular weight 362.84 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Zinc(II) (R,Z)-12-hydroxyoctadec-9-enoate (C18H33O3Zn) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
