Description
As a certified reference material (CRM), 4-Formylphenyl [1,1'-biphenyl]-4-carboxylate 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.
CATO supplies 4-Formylphenyl [1,1'-biphenyl]-4-carboxylate (CAS 303058-49-3), a certified reference material (molecular formula C20H14O3, MW 302.32 g/mol) for analytical method development and quality control.
Structurally, 4-Formylphenyl [1,1'-biphenyl]-4-carboxylate (C20H14O3) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 302.32 g/mol, it falls into the moderately-high-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.
