Compared with other compounds in its class, the molecular weight of 203.24 g/mol gives 4-((3,5-Dimethylisoxazol-4-yl)methyl)phenol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4-((3,5-Dimethylisoxazol-4-yl)methyl)phenol (CAS 75999-06-3), a certified reference material (molecular formula C12H13NO2, MW 203.24 g/mol) for analytical method development and quality control.
The molecular framework of 4-((3,5-Dimethylisoxazol-4-yl)methyl)phenol (C12H13NO2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 4-((3,5-Dimethylisoxazol-4-yl)methyl)phenol 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.
