Chemical Structure

4-((1H-imidazol-1-yl)methyl)-5-methylisoxazole-3-carboxylic acid hydrochloride CAS 1177339-58-0 chemical structure

Description

The occurrence of 4-((1H-imidazol-1-yl)methyl)-5-methylisoxazole-3-carboxylic acid 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.

4-((1H-imidazol-1-yl)methyl)-5-methylisoxazole-3-carboxylic acid hydrochloride (CAS 1177339-58-0), molecular formula C9H9N3O3HCl and molecular weight 243.65 g/mol, is a CATO reference standard with documented purity and traceability.

4-((1H-imidazol-1-yl)methyl)-5-methylisoxazole-3-carboxylic acid hydrochloride (C9H9N3O3HCl) 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).

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 4-((1H-imidazol-1-yl)methyl)-5-methylisoxazole-3-carboxylic acid 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.
