2-(2-Hydroxy-5-tert-octylphenyl)benzotriazole CAS 3147-75-9

Description

The occurrence of 2-(2-Hydroxy-5-tert-octylphenyl)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.

2-(2-Hydroxy-5-tert-octylphenyl)benzotriazole (CAS 3147-75-9) is a high-purity analytical reference standard with the molecular formula C20H25N3O and a molecular weight of 323.43 g/mol.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 2-(2-Hydroxy-5-tert-octylphenyl)benzotriazole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 323.43 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 2-(2-Hydroxy-5-tert-octylphenyl)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.
