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 ethan-1,1,2,2-d4-ol, 2-(benzylmethoxy)-.
ethan-1,1,2,2-d4-ol, 2-(benzylmethoxy)- (CAS 87867-14-9) is a high-purity analytical reference standard with the molecular formula C9H8D4O2 and a molecular weight of 156.22 g/mol.
Owing to deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, ethan-1,1,2,2-d4-ol, 2-(benzylmethoxy)- is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 156.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
