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 [1,1':4',1'':4'',1'''-Quaterphenyl]-2-carbaldehyde (CAS 3365-18-2), a certified reference material (molecular formula C25H18O, MW 334.41 g/mol) for analytical method development and quality control.
Structurally, [1,1':4',1'':4'',1'''-Quaterphenyl]-2-carbaldehyde (C25H18O) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 17.0, corresponding to approximately 17 ring(s) or double-bond equivalent(s). With a molecular weight of 334.41 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',1'':4'',1'''-Quaterphenyl]-2-carbaldehyde 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.
