2-Amino-4-(5-ethyl-1,3,4-oxadiazol-2-yl)phenol CAS 1091990-97-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Amino-4-(5-ethyl-1,3,4-oxadiazol-2-yl)phenol.

2-Amino-4-(5-ethyl-1,3,4-oxadiazol-2-yl)phenol (CAS 1091990-97-4), molecular formula C10H11N3O2 and molecular weight 205.21 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2-Amino-4-(5-ethyl-1,3,4-oxadiazol-2-yl)phenol (C10H11N3O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 205.21 g/mol, it falls into the medium-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.

As a certified reference material (CRM), 2-Amino-4-(5-ethyl-1,3,4-oxadiazol-2-yl)phenol 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.
