4-(2-Nitro-4-(1H-pyrazol-5-yl)phenyl)morpholine CAS 1033847-04-9

Description

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.

4-(2-Nitro-4-(1H-pyrazol-5-yl)phenyl)morpholine (CAS 1033847-04-9), molecular formula C13H14N4O3 and molecular weight 274.28 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-(2-Nitro-4-(1H-pyrazol-5-yl)phenyl)morpholine (C13H14N4O3) 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.

As a certified reference material (CRM), 4-(2-Nitro-4-(1H-pyrazol-5-yl)phenyl)morpholine 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.
