Chemical Structure

1,5,8-Trimethyltetralin CAS 21693-51-6 chemical structure

Description

1,5,8-Trimethyltetralin (C13H18) contains an aromatic ring system. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

1,5,8-Trimethyltetralin (CAS 21693-51-6), molecular formula C13H18 and molecular weight 174.28 g/mol, is a CATO reference standard with documented purity and traceability.

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), 1,5,8-Trimethyltetralin 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.
