5-Amino-n'-hydroxy-1-methyl-1h-pyrazole-4-carboximidamide CAS 62564-69-6

Description

The occurrence of 5-Amino-n'-hydroxy-1-methyl-1h-pyrazole-4-carboximidamide is closely related to an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-Amino-n'-hydroxy-1-methyl-1h-pyrazole-4-carboximidamide (CAS 62564-69-6), molecular formula C5H9N5O and molecular weight 155.16 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, a hydroxyl group, an ether linkage, 5-Amino-n'-hydroxy-1-methyl-1h-pyrazole-4-carboximidamide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 155.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
