Description
As a certified reference material (CRM), 2-(3-Ethoxy-4-nitro-1h-pyrazol-1-yl)ethan-1-amine hydrochloride 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.
2-(3-Ethoxy-4-nitro-1h-pyrazol-1-yl)ethan-1-amine hydrochloride (CAS 1417570-01-4) is a high-purity analytical reference standard with the molecular formula C7H12N4O3HCl and a molecular weight of 236.66 g/mol.
Structurally, 2-(3-Ethoxy-4-nitro-1h-pyrazol-1-yl)ethan-1-amine hydrochloride (C7H12N4O3HCl) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 236.66 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.
