Description
CATO supplies 6-[(E)-2-(4-Methylphenyl)ethenyl]-4-[(Z)-2-(4-methylphenyl)ethenyl]-2-{[(2-methylphenyl)methyl]sulfanyl}pyridine-3-carbonitrile (CAS 303985-39-9), a certified reference material (molecular formula C32H28N2S, MW 472.64 g/mol) for analytical method development and quality control.
Structurally, 6-[(E)-2-(4-Methylphenyl)ethenyl]-4-[(Z)-2-(4-methylphenyl)ethenyl]-2-{[(2-methylphenyl)methyl]sulfanyl}pyridine-3-carbonitrile (C32H28N2S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 20.0, corresponding to approximately 20 ring(s) or double-bond equivalent(s). With a molecular weight of 472.64 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.
As a certified reference material (CRM), 6-[(E)-2-(4-Methylphenyl)ethenyl]-4-[(Z)-2-(4-methylphenyl)ethenyl]-2-{[(2-methylphenyl)methyl]sulfanyl}pyridine-3-carbonitrile 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.
