Chemical Structure

2,2,5,7,8-Pentamethylchroman CAS 55646-01-0 chemical structure

Description

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.

2,2,5,7,8-Pentamethylchroman (CAS 55646-01-0), molecular formula C14H20O and molecular weight 204.31 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2,2,5,7,8-Pentamethylchroman (C14H20O) contains a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 204.31 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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