5-Amino-1,3-dimethylpyrazole 1,3-dimethyl-1h-pyrazol-5-amine 5-amino-1,3-dimethyl-1h-pyrazole 2,5-dimethyl-2h-pyrazol-3-ylamine 1,3-dimethyl-1h-pyrazole-5-amine 3-amino-2,5-dimethyl-2h-pyrazole 1,3-dimethyl-1h-pyrazole-5yl-amine 3524-32-1 (CAS 3524-32-1), molecular formula C5H13N3 and molecular weight 115.18 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 5-Amino-1,3-dimethylpyrazole 1,3-dimethyl-1h-pyrazol-5-amine 5-amino-1,3-dimethyl-1h-pyrazole 2,5-dimethyl-2h-pyrazol-3-ylamine 1,3-dimethyl-1h-pyrazole-5-amine 3-amino-2,5-dimethyl-2h-pyrazole 1,3-dimethyl-1h-pyrazole-5yl-amine 3524-32-1 (C5H13N3) is characterized by an organic framework. 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.

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.
