Chemical Structure

2,6,6-Trimethylcyclohex-2-en-4-ol-1-one CAS 19620-37-2 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.

2,6,6-Trimethylcyclohex-2-en-4-ol-1-one (CAS 19620-37-2), molecular formula C9H14O2 and molecular weight 154.21 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 2,6,6-Trimethylcyclohex-2-en-4-ol-1-one is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 154.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 2,6,6-Trimethylcyclohex-2-en-4-ol-1-one 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.
