Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO supplies 4369-55-5 5-Amino-3-phenylisoxazole 5-Isoxazolamine, 3-phenyl- ISOXAZOLE, 5-AMINO-3-PHENYL UPJOHN U-10776 Isoxazole, 5-amino-3-phenyl- NSC-93157 NSC93157 U 10776 (CAS 4369-55-5), a certified reference material (molecular formula C9H18N2O, MW 170.25 g/mol) for analytical method development and quality control.

The molecular framework of 4369-55-5 5-Amino-3-phenylisoxazole 5-Isoxazolamine, 3-phenyl- ISOXAZOLE, 5-AMINO-3-PHENYL UPJOHN U-10776 Isoxazole, 5-amino-3-phenyl- NSC-93157 NSC93157 U 10776 (C9H18N2O) is characterized by an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
