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.
(R)-2-((2-((tert-Butyldimethylsilyl)oxy)-2-(4-fluorophenyl)ethyl)thio)acetic acid (CAS 956368-72-2) is a high-purity analytical reference standard with the molecular formula C16H25FO3SSi and a molecular weight of 344.52 g/mol.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, (R)-2-((2-((tert-Butyldimethylsilyl)oxy)-2-(4-fluorophenyl)ethyl)thio)acetic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 344.52 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
As a certified reference material (CRM), (R)-2-((2-((tert-Butyldimethylsilyl)oxy)-2-(4-fluorophenyl)ethyl)thio)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.
