Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including ((2S,4R)-4-((tert-Butyldiphenylsilyl)oxy)pyrrolidin-2-yl)bis(3,5-dimethylphenyl)methanol.
((2S,4R)-4-((tert-Butyldiphenylsilyl)oxy)pyrrolidin-2-yl)bis(3,5-dimethylphenyl)methanol (CAS 1859968-66-3), molecular formula C37H45NO2Si and molecular weight 563.84 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, ((2S,4R)-4-((tert-Butyldiphenylsilyl)oxy)pyrrolidin-2-yl)bis(3,5-dimethylphenyl)methanol is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 563.84 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), ((2S,4R)-4-((tert-Butyldiphenylsilyl)oxy)pyrrolidin-2-yl)bis(3,5-dimethylphenyl)methanol 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.
