Chemical Structure

1-Methoxy-2-(methylsulfonyl)benzene CAS 13736-79-3 chemical structure

Description

The occurrence of 1-Methoxy-2-(methylsulfonyl)benzene is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-Methoxy-2-(methylsulfonyl)benzene (CAS 13736-79-3) is a high-purity analytical reference standard with the molecular formula C8H10O3S and a molecular weight of 186.23 g/mol.

Structurally, 1-Methoxy-2-(methylsulfonyl)benzene (C8H10O3S) contains a sulfone group, a carboxylic acid group, 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 186.23 g/mol, it falls into the medium-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), 1-Methoxy-2-(methylsulfonyl)benzene 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.
