Chemical Structure
Description
(S)-2-Amino-2-(5-fluoro-2-hydroxyphenyl)acetic acid hydrochloride (C8H8FNO3HCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
(S)-2-Amino-2-(5-fluoro-2-hydroxyphenyl)acetic acid hydrochloride (CAS 2241594-44-3) is a high-purity analytical reference standard with the molecular formula C8H8FNO3HCl and a molecular weight of 221.61 g/mol.
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.
