Chemical Structure

1H-Phenalene CAS 203-80-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 166.22 g/mol gives 1H-Phenalene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1H-Phenalene (CAS 203-80-5), molecular formula C13H10 and molecular weight 166.22 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 1H-Phenalene (C13H10) contains an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 166.22 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.

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), 1H-Phenalene 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.
