Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (4S)-4,5-Dihydro-4-phenyl-2-oxazolamine (S)-4,5-Dihydro-4-phenyl-2-oxazolamine (S)-Rexamino 165035-65-4.

(4S)-4,5-Dihydro-4-phenyl-2-oxazolamine (S)-4,5-Dihydro-4-phenyl-2-oxazolamine (S)-Rexamino 165035-65-4 (CAS 165035-65-4) is a high-purity analytical reference standard with the molecular formula C9H10N2O and a molecular weight of 162.19 g/mol.

(4S)-4,5-Dihydro-4-phenyl-2-oxazolamine (S)-4,5-Dihydro-4-phenyl-2-oxazolamine (S)-Rexamino 165035-65-4 (C9H10N2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. Its physicochemical properties are representative of its class; 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.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
