Description
CATO supplies Phenoxy-d5-acetic Acid Ethyl Ester (CAS 1189442-18-9), a certified reference material (molecular formula C10H7D5O3, MW 185.23 g/mol) for analytical method development and quality control.
Based on its molecular formula C10H7D5O3, Phenoxy-d5-acetic Acid Ethyl Ester contains deuterium isotope labeling, 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 185.23 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), Phenoxy-d5-acetic Acid Ethyl Ester 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.
