Chemical Structure

Copper naphthenate CAS 1338-02-9 chemical structure

Description

Copper naphthenate (CAS 1338-02-9), molecular formula C10H17O2Cu and molecular weight 232.79 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Copper naphthenate (C10H17O2Cu) 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.

As a certified reference material (CRM), Copper naphthenate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
