Chemical Structure
Description
The occurrence of 2-(3,5-Di-tert-amyl-2-hydroxyphenyl)benzotriazole is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2-(3,5-Di-tert-amyl-2-hydroxyphenyl)benzotriazole (CAS 25973-55-1), a certified reference material (molecular formula C22H29N3O, MW 351.49 g/mol) for analytical method development and quality control.
The molecular framework of 2-(3,5-Di-tert-amyl-2-hydroxyphenyl)benzotriazole (C22H29N3O) is characterized by a steroid core, 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), 2-(3,5-Di-tert-amyl-2-hydroxyphenyl)benzotriazole 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.
