4-Chlorophenyl methanesulfonate CAS 6317-27-7

Description

Compared with other compounds in its class, the molecular weight of 206.65 g/mol gives 4-Chlorophenyl methanesulfonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-Chlorophenyl methanesulfonate (CAS 6317-27-7), molecular formula C7H7ClO3S and molecular weight 206.65 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 4-Chlorophenyl methanesulfonate (C7H7ClO3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 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 206.65 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), 4-Chlorophenyl methanesulfonate 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.
