1-(4-chlorophenyl)-1H,4H,5H,6H,7H,8H-cyclohepta[c]pyrazole-3-carboxylic acid CAS 97438-03-4

Description

1-(4-chlorophenyl)-1H,4H,5H,6H,7H,8H-cyclohepta[c]pyrazole-3-carboxylic acid (C15H15ClN2O2) 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, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

1-(4-chlorophenyl)-1H,4H,5H,6H,7H,8H-cyclohepta[c]pyrazole-3-carboxylic acid (CAS 97438-03-4), molecular formula C15H15ClN2O2 and molecular weight 290.74 g/mol, is a CATO reference standard with documented purity and traceability.

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.
