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 (S)-2-amino-3-(4-(2-bromoethoxy)phenyl)propanoic acid hydrochloride.
(S)-2-amino-3-(4-(2-bromoethoxy)phenyl)propanoic acid hydrochloride (CAS 481052-60-2), molecular formula C11H14BrNO3HCl and molecular weight 324.60 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (S)-2-amino-3-(4-(2-bromoethoxy)phenyl)propanoic acid hydrochloride (C11H14BrNO3HCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 324.60 g/mol, it falls into the moderately-high-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.
