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-Chloro-2-(((2E)-1-oxo-3-(4-pentylphenyl)-2-propen-1-yl)amino)benzoic Acid.
4-Chloro-2-(((2E)-1-oxo-3-(4-pentylphenyl)-2-propen-1-yl)amino)benzoic Acid (CAS 99754-06-0), molecular formula C21H34ClNO3 and molecular weight 383.95 g/mol, is a CATO reference standard with documented purity and traceability.
4-Chloro-2-(((2E)-1-oxo-3-(4-pentylphenyl)-2-propen-1-yl)amino)benzoic Acid (C21H34ClNO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 4-Chloro-2-(((2E)-1-oxo-3-(4-pentylphenyl)-2-propen-1-yl)amino)benzoic Acid 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.
