Chemical Structure
Description
4-Hydroxyphenyl pivalate (CAS 67258-88-2) is a high-purity analytical reference standard with the molecular formula C11H14O3 and a molecular weight of 194.23 g/mol.
Based on its molecular formula C11H14O3, 4-Hydroxyphenyl pivalate contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 194.23 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
As a certified reference material (CRM), 4-Hydroxyphenyl pivalate 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.
