4-Ethyl-2-methoxy-5-methylphenol CAS 120550-71-2

Description

Compared with other compounds in its class, the molecular weight of 166.22 g/mol gives 4-Ethyl-2-methoxy-5-methylphenol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-Ethyl-2-methoxy-5-methylphenol (CAS 120550-71-2) is a high-purity analytical reference standard with the molecular formula C10H14O2 and a molecular weight of 166.22 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 4-Ethyl-2-methoxy-5-methylphenol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 166.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), 4-Ethyl-2-methoxy-5-methylphenol 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.
