Chemical Structure
Description
1-[(3,4-dimethoxyphenyl)methyl]-1H-pyrazol-4-amine hydrochloride (C12H15N3O2HCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
1-[(3,4-dimethoxyphenyl)methyl]-1H-pyrazol-4-amine hydrochloride (CAS 1803600-64-7) is a high-purity analytical reference standard with the molecular formula C12H15N3O2HCl and a molecular weight of 269.73 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-[(3,4-dimethoxyphenyl)methyl]-1H-pyrazol-4-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.
