Chemical Structure

6-Methyl-3-oxoheptanenitrile CAS 660448-95-3 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.

6-Methyl-3-oxoheptanenitrile (CAS 660448-95-3), molecular formula C8H13NO and molecular weight 139.19 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 6-Methyl-3-oxoheptanenitrile (C8H13NO) is characterized by an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

As a certified reference material (CRM), 6-Methyl-3-oxoheptanenitrile 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.
