Chemical Structure
Description
2'-(Methylsulfinyl)-[1,1'-biphenyl]-4-carbaldehyde (CAS 1171155-44-4), molecular formula C14H12O2S and molecular weight 244.31 g/mol, is a CATO reference standard with documented purity and traceability.
2'-(Methylsulfinyl)-[1,1'-biphenyl]-4-carbaldehyde (C14H12O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
CATO manufactures 2'-(Methylsulfinyl)-[1,1'-biphenyl]-4-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.
