N-(3,5-Diethyl-1-methyl-1H-pyrazol-4-yl)-2-methoxyacetamide CAS 87675-92-1 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 N-(3,5-Diethyl-1-methyl-1H-pyrazol-4-yl)-2-methoxyacetamide.

N-(3,5-Diethyl-1-methyl-1H-pyrazol-4-yl)-2-methoxyacetamide (CAS 87675-92-1), molecular formula C11H19N3O2 and molecular weight 225.29 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of N-(3,5-Diethyl-1-methyl-1H-pyrazol-4-yl)-2-methoxyacetamide (C11H19N3O2) is characterized by an amino-acid-derived structure, 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. 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), N-(3,5-Diethyl-1-methyl-1H-pyrazol-4-yl)-2-methoxyacetamide 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.
