Chemical Structure
Description
2-(5-(tert-Butyl)isoxazol-4-yl)acetonitrile (CAS 155602-45-2), molecular formula C9H12N2O and molecular weight 164.20 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(5-(tert-Butyl)isoxazol-4-yl)acetonitrile (C9H12N2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing 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).
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.
CATO manufactures 2-(5-(tert-Butyl)isoxazol-4-yl)acetonitrile under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
