5-(3-Chloro-4-methoxyphenyl)-1H-pyrazol-3-amine hydrochloride CAS 1031793-11-9 chemical structure

Description

The occurrence of 5-(3-Chloro-4-methoxyphenyl)-1H-pyrazol-3-amine hydrochloride is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-(3-Chloro-4-methoxyphenyl)-1H-pyrazol-3-amine hydrochloride (CAS 1031793-11-9), molecular formula C10H10ClN3OHCl and molecular weight 260.12 g/mol, is a CATO reference standard with documented purity and traceability.

5-(3-Chloro-4-methoxyphenyl)-1H-pyrazol-3-amine hydrochloride (C10H10ClN3OHCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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).

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.

CATO manufactures 5-(3-Chloro-4-methoxyphenyl)-1H-pyrazol-3-amine hydrochloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
