Description

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.

2-((4-Methoxyphenyl)thio)-1,1-diphenylethan-1-ol (CAS 303152-46-7), molecular formula C21H20O2S and molecular weight 336.45 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2-((4-Methoxyphenyl)thio)-1,1-diphenylethan-1-ol (C21H20O2S) contains a steroid core, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 336.45 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

As a certified reference material (CRM), 2-((4-Methoxyphenyl)thio)-1,1-diphenylethan-1-ol 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.
