5-Amino-1-(benzo[d]oxazol-2-yl)-2,3-dihydro-1H-pyrazole-4-carbonitrile CAS 1033463-25-0

Description

The occurrence of 5-Amino-1-(benzo[d]oxazol-2-yl)-2,3-dihydro-1H-pyrazole-4-carbonitrile is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-Amino-1-(benzo[d]oxazol-2-yl)-2,3-dihydro-1H-pyrazole-4-carbonitrile (CAS 1033463-25-0) is a high-purity analytical reference standard with the molecular formula C11H9N5O and a molecular weight of 227.22 g/mol.

The molecular framework of 5-Amino-1-(benzo[d]oxazol-2-yl)-2,3-dihydro-1H-pyrazole-4-carbonitrile (C11H9N5O) is characterized by a nitrogen-containing heterocyclic scaffold, 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.

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), 5-Amino-1-(benzo[d]oxazol-2-yl)-2,3-dihydro-1H-pyrazole-4-carbonitrile 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.
