Prop-2-yn-1-yl 3-bromo-4-((4-methylbenzyl)oxy)benzoate (CAS 1706456-44-1), molecular formula C18H15BrO3 and molecular weight 359.21 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Prop-2-yn-1-yl 3-bromo-4-((4-methylbenzyl)oxy)benzoate (C18H15BrO3) is characterized by a steroid core, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO manufactures Prop-2-yn-1-yl 3-bromo-4-((4-methylbenzyl)oxy)benzoate 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.
