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 5-Amino-2-(1-hydroxyethyl)oxazole-4-carbonitrile.
5-Amino-2-(1-hydroxyethyl)oxazole-4-carbonitrile (CAS 907552-46-9), molecular formula C6H7N3O2 and molecular weight 153.14 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 5-Amino-2-(1-hydroxyethyl)oxazole-4-carbonitrile (C6H7N3O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 153.14 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
