Chemical Structure
Description
(1R)-1-(oxepan-4-yl)ethanol (CAS 2291677-98-8), molecular formula C8H16O2 and molecular weight 144.21 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, (1R)-1-(oxepan-4-yl)ethanol is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 144.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
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.
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.
