Chemical Structure

3-Methyl-4-octanone CAS 20754-04-5 chemical structure

Description

3-Methyl-4-octanone (CAS 20754-04-5), molecular formula C9H18O and molecular weight 142.24 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 3-Methyl-4-octanone (C9H18O) contains a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 142.24 g/mol, it falls into the low-molecular-weight range.

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), 3-Methyl-4-octanone 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.
