Chemical Structure

1-Ethyl-N-((5-fluorothiophen-2-yl)methyl)-5-methyl-1H-pyrazol-4-amine hydrochloride CAS 1856041-13-8 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-Ethyl-N-((5-fluorothiophen-2-yl)methyl)-5-methyl-1H-pyrazol-4-amine hydrochloride.

1-Ethyl-N-((5-fluorothiophen-2-yl)methyl)-5-methyl-1H-pyrazol-4-amine hydrochloride (CAS 1856041-13-8), molecular formula C11H14FN3SHCl and molecular weight 275.77 g/mol, is a CATO reference standard with documented purity and traceability.

1-Ethyl-N-((5-fluorothiophen-2-yl)methyl)-5-methyl-1H-pyrazol-4-amine hydrochloride (C11H14FN3SHCl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine/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 1-Ethyl-N-((5-fluorothiophen-2-yl)methyl)-5-methyl-1H-pyrazol-4-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.
