{4-[(Methylsulfonyl)oxy]phenyl}acetic acid CAS 64369-79-5

Description

Compared with other compounds in its class, the molecular weight of 230.24 g/mol gives {4-[(Methylsulfonyl)oxy]phenyl}acetic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

{4-[(Methylsulfonyl)oxy]phenyl}acetic acid (CAS 64369-79-5) is a high-purity analytical reference standard with the molecular formula C9H10O5S and a molecular weight of 230.24 g/mol.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, {4-[(Methylsulfonyl)oxy]phenyl}acetic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 230.24 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-[(Methylsulfonyl)oxy]phenyl}acetic acid 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.
