Chemical Structure
Description
2-(2-Hydroxyethoxy)ethyl Benzoate (CAS 20587-61-5), molecular formula C11H20O4 and molecular weight 216.27 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 2-(2-Hydroxyethoxy)ethyl Benzoate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 216.27 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.
