4-chloro-1,3-dimethyl-1H-pyrazol-5-amine hydrochloride CAS 1909336-62-4

Description

Compared with other compounds in its class, the molecular weight of 182.05 g/mol gives 4-chloro-1,3-dimethyl-1H-pyrazol-5-amine hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 4-chloro-1,3-dimethyl-1H-pyrazol-5-amine hydrochloride (CAS 1909336-62-4), a certified reference material (molecular formula C5H8ClN3HCl, MW 182.05 g/mol) for analytical method development and quality control.

Based on its molecular formula C5H8ClN3HCl, 4-chloro-1,3-dimethyl-1H-pyrazol-5-amine hydrochloride contains a nitrile group, chlorine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 182.05 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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), 4-chloro-1,3-dimethyl-1H-pyrazol-5-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.
