1-((4-Nitro-1h-pyrazol-1-yl)methyl)-1h-pyrazole-4-carboxylic acid CAS 1006441-58-2

Description

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 1-((4-Nitro-1h-pyrazol-1-yl)methyl)-1h-pyrazole-4-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 237.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

1-((4-Nitro-1h-pyrazol-1-yl)methyl)-1h-pyrazole-4-carboxylic acid (CAS 1006441-58-2) is a high-purity analytical reference standard with the molecular formula C8H7N5O4 and a molecular weight of 237.17 g/mol.

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), 1-((4-Nitro-1h-pyrazol-1-yl)methyl)-1h-pyrazole-4-carboxylic acid 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.
