Chemical Structure
Description
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.
4-((1-(Bromomethyl)cycloheptyl)oxy)tetrahydro-2h-pyran (CAS 1250628-18-2) is a high-purity analytical reference standard with the molecular formula C13H23BrO2 and a molecular weight of 291.22 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, 4-((1-(Bromomethyl)cycloheptyl)oxy)tetrahydro-2h-pyran is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 291.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
