Chemical Structure

1,3,6-Trimethylpyrene CAS 27979-20-0 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.

1,3,6-Trimethylpyrene (CAS 27979-20-0), molecular formula C19H16 and molecular weight 244.33 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 1,3,6-Trimethylpyrene (C19H16) contains a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 244.33 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
