(S)-O-Acetylmandelic Acid CAS 7322-88-5

Description

Compared with other compounds in its class, the molecular weight of 194.18 g/mol gives (S)-O-Acetylmandelic Acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(S)-O-Acetylmandelic Acid (CAS 7322-88-5), molecular formula C10H10O4 and molecular weight 194.18 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C10H10O4, (S)-O-Acetylmandelic Acid contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 194.18 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), (S)-O-Acetylmandelic 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.
