Chemical Structure
Description
Vitamin E Related Compound 1 (2-Methyl-2-(4,8,12-Trimethyltridecyl)-6-Chromanol) (CAS 119-98-2), molecular formula C26H44O2 and molecular weight 388.63 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Vitamin E Related Compound 1 (2-Methyl-2-(4,8,12-Trimethyltridecyl)-6-Chromanol) (C26H44O2) is characterized by a steroid core, 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 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), Vitamin E Related Compound 1 (2-Methyl-2-(4,8,12-Trimethyltridecyl)-6-Chromanol) 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.
