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 (2R,4R)-rel-2,4-Bis(2’,4’-difluorophenyl)-2,4-dihydroxypentane.
CATO supplies (2R,4R)-rel-2,4-Bis(2’,4’-difluorophenyl)-2,4-dihydroxypentane (CAS 1329616-28-5), a certified reference material (molecular formula C17H16F4O2, MW 328.30 g/mol) for analytical method development and quality control.
(2R,4R)-rel-2,4-Bis(2’,4’-difluorophenyl)-2,4-dihydroxypentane (C17H16F4O2) contains a steroid core, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 (2R,4R)-rel-2,4-Bis(2’,4’-difluorophenyl)-2,4-dihydroxypentane 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.
