Chemical Structure
Description
The occurrence of 2,7-Difluoro-8-((triisopropylsilyl)ethynyl)naphthalen-1-yl trifluoromethanesulfonate is closely related to a steroid core, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2,7-Difluoro-8-((triisopropylsilyl)ethynyl)naphthalen-1-yl trifluoromethanesulfonate (CAS 2852767-38-3), a certified reference material (molecular formula C22H25F5O3SSi, MW 492.57 g/mol) for analytical method development and quality control.
Owing to a steroid core, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution, 2,7-Difluoro-8-((triisopropylsilyl)ethynyl)naphthalen-1-yl trifluoromethanesulfonate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 492.57 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
