Chemical Structure
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.
CATO supplies 8-((Triisopropylsilyl)ethynyl)naphthalen-1-yl trifluoromethanesulfonate (CAS 2135543-95-0), a certified reference material (molecular formula C22H27F3O3SSi, MW 456.59 g/mol) for analytical method development and quality control.
Structurally, 8-((Triisopropylsilyl)ethynyl)naphthalen-1-yl trifluoromethanesulfonate (C22H27F3O3SSi) contains a steroid core, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 456.59 g/mol, it falls into the moderately-high-molecular-weight range. 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), 8-((Triisopropylsilyl)ethynyl)naphthalen-1-yl trifluoromethanesulfonate 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.
