1-Ethyl-2-methylcyclohexane CAS 3728-54-9

Description

The occurrence of 1-Ethyl-2-methylcyclohexane is closely related to an organic framework in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-Ethyl-2-methylcyclohexane (CAS 3728-54-9), molecular formula C9H18 and molecular weight 126.24 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an organic framework, 1-Ethyl-2-methylcyclohexane is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 126.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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), 1-Ethyl-2-methylcyclohexane 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.
