Chemical Structure

7-cis-Nonadecenoic acid CAS 118020-79-4 chemical structure

Description

CATO manufactures 7-cis-Nonadecenoic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

7-cis-Nonadecenoic acid (CAS 118020-79-4), molecular formula C19H36O2 and molecular weight 296.49 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 7-cis-Nonadecenoic acid (C19H36O2) 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.
