Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 67533-12-4 7778AH C8H20N.C2H3O2.4H2O Tetraethylammonium acetate tetrahydrate.
CATO supplies 67533-12-4 7778AH C8H20N.C2H3O2.4H2O Tetraethylammonium acetate tetrahydrate (CAS 67533-12-4), a certified reference material (molecular formula C8H20NC2H3O2H2O, MW 207.31 g/mol) for analytical method development and quality control.
Structurally, 67533-12-4 7778AH C8H20N.C2H3O2.4H2O Tetraethylammonium acetate tetrahydrate (C8H20NC2H3O2H2O) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of -1.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 207.31 g/mol, it falls into the medium-molecular-weight range. 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.
