Chemical Structure

3-ethyl-4-methylpentanoic acid CAS 60308-89-6 chemical structure

Description

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.

3-ethyl-4-methylpentanoic acid (CAS 60308-89-6), molecular formula C8H16O2 and molecular weight 144.21 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3-ethyl-4-methylpentanoic acid (C8H16O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

As a certified reference material (CRM), 3-ethyl-4-methylpentanoic acid 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.
