Chemical Structure
Description
The molecular framework of Potassium Ethyl-p-hydroxyl Benzoate Solution, 100pm (C9H9O3K) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Potassium Ethyl-p-hydroxyl Benzoate Solution, 100pm (CAS 36457-19-9) is a high-purity analytical reference standard with the molecular formula C9H9O3K and a molecular weight of 204.27 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), Potassium Ethyl-p-hydroxyl Benzoate Solution, 100pm 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.
