Chemical Structure
Description
As a certified reference material (CRM), 3-Amino-5-methoxyisoxazole meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
3-Amino-5-methoxyisoxazole (CAS 32326-25-3) is a high-purity analytical reference standard with the molecular formula C4H6N2O2 and a molecular weight of 114.10 g/mol.
Structurally, 3-Amino-5-methoxyisoxazole (C4H6N2O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 114.10 g/mol, it falls into the low-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
