Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1,1,4,4-tetraphenyl-1,3-butadiene (CAS 1450-63-1), molecular formula C28H46 and molecular weight 382.66 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1,1,4,4-tetraphenyl-1,3-butadiene (C28H46) 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 382.66 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).
CATO manufactures 1,1,4,4-tetraphenyl-1,3-butadiene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
