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.
1-((3-Bromo-4-methoxyphenyl)sulfonyl)-4-((tert-butyldiphenylsilyl)oxy)piperidine (CAS 1704081-29-7), molecular formula C28H34BrNO4SSi and molecular weight 588.63 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution, 1-((3-Bromo-4-methoxyphenyl)sulfonyl)-4-((tert-butyldiphenylsilyl)oxy)piperidine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 588.63 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), 1-((3-Bromo-4-methoxyphenyl)sulfonyl)-4-((tert-butyldiphenylsilyl)oxy)piperidine 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.
