Chemical Structure

4-Ethyl-2-methylphenol CAS 2219-73-0 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Ethyl-2-methylphenol.

4-Ethyl-2-methylphenol (CAS 2219-73-0) is a high-purity analytical reference standard with the molecular formula C9H12O and a molecular weight of 136.19 g/mol.

Structurally, 4-Ethyl-2-methylphenol (C9H12O) contains a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 136.19 g/mol, it falls into the low-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 4-Ethyl-2-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.
