Chemical Structure

3-Ethyltoluene CAS 620-14-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 120.19 g/mol gives 3-Ethyltoluene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-Ethyltoluene (CAS 620-14-4), molecular formula C9H12 and molecular weight 120.19 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 3-Ethyltoluene (C9H12) contains 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 120.19 g/mol, it falls into the low-molecular-weight range. 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).

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), 3-Ethyltoluene 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.
