Chemical Structure

β-Methylstyrene (cis- and trans- mixture) (stabilized with TBC) CAS 637-50-3 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.

CATO supplies β-Methylstyrene (cis- and trans- mixture) (stabilized with TBC) (CAS 637-50-3), a certified reference material (molecular formula C9H10, MW 118.18 g/mol) for analytical method development and quality control.

β-Methylstyrene (cis- and trans- mixture) (stabilized with TBC) (C9H10) contains an aromatic ring system. Its physicochemical properties are representative of its class; 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).

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.
