Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-[(E)-[(Thiophen-2-yl)methylidene]amino]phenyl 4-fluorobenzene-1-sulfonate.
CATO supplies 4-[(E)-[(Thiophen-2-yl)methylidene]amino]phenyl 4-fluorobenzene-1-sulfonate (CAS 329778-38-3), a certified reference material (molecular formula C17H12FNO3S2, MW 361.41 g/mol) for analytical method development and quality control.
4-[(E)-[(Thiophen-2-yl)methylidene]amino]phenyl 4-fluorobenzene-1-sulfonate (C17H12FNO3S2) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 4-[(E)-[(Thiophen-2-yl)methylidene]amino]phenyl 4-fluorobenzene-1-sulfonate 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.
