(2e)-3-(5-Chloro-3-methyl-1-phenyl-1h-pyrazol-4-yl)prop-2-enoic acid CAS 27268-07-1

Description

(2e)-3-(5-Chloro-3-methyl-1-phenyl-1h-pyrazol-4-yl)prop-2-enoic acid (C13H11ClN2O2) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

(2e)-3-(5-Chloro-3-methyl-1-phenyl-1h-pyrazol-4-yl)prop-2-enoic acid (CAS 27268-07-1) is a high-purity analytical reference standard with the molecular formula C13H11ClN2O2 and a molecular weight of 262.69 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), (2e)-3-(5-Chloro-3-methyl-1-phenyl-1h-pyrazol-4-yl)prop-2-enoic acid 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.
