4-Bromo-6-fluoro-5-((triisopropylsilyl)ethynyl)naphthalen-2-ol CAS 2757097-48-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 421.42 g/mol gives 4-Bromo-6-fluoro-5-((triisopropylsilyl)ethynyl)naphthalen-2-ol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 4-Bromo-6-fluoro-5-((triisopropylsilyl)ethynyl)naphthalen-2-ol (CAS 2757097-48-4), a certified reference material (molecular formula C21H26BrFOSi, MW 421.42 g/mol) for analytical method development and quality control.

4-Bromo-6-fluoro-5-((triisopropylsilyl)ethynyl)naphthalen-2-ol (C21H26BrFOSi) contains a steroid core, a hydroxyl group, an ether linkage, fluorine/bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
