Chemical Structure

Hydrogenatedstyrene-butadienepolymer CAS 66070-58-4 chemical structure

Description

CATO supplies Hydrogenatedstyrene-butadienepolymer (CAS 66070-58-4), a certified reference material (molecular formula C8H8C4H6C2H4, MW 186.30 g/mol) for analytical method development and quality control.

Structurally, Hydrogenatedstyrene-butadienepolymer (C8H8C4H6C2H4) contains an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 186.30 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), Hydrogenatedstyrene-butadienepolymer 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.
