Chemical Structure

1,3,4-Trimethylphenanthrene CAS 66271-45-2 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

1,3,4-Trimethylphenanthrene (CAS 66271-45-2), molecular formula C17H16 and molecular weight 220.31 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 1,3,4-Trimethylphenanthrene (C17H16) contains a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 220.31 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

As a certified reference material (CRM), 1,3,4-Trimethylphenanthrene 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.
