Chemical Structure
Description
1,4-Bis-(2-methylstyryl)benzene (CAS 13280-61-0), molecular formula C24H40 and molecular weight 328.57 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1,4-Bis-(2-methylstyryl)benzene (C24H40) contains 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 328.57 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), 1,4-Bis-(2-methylstyryl)benzene 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.
