CATO supplies (E)-2,2-Dimethyl-propanoic Acid 4-[4-Chloro-1-(4-hydroxyphenyl)-2-phenyl-1-butenyl]phenyl Ester (CAS 177748-18-4), a certified reference material (molecular formula C27H27ClO3, MW 434.95 g/mol) for analytical method development and quality control.
Structurally, (E)-2,2-Dimethyl-propanoic Acid 4-[4-Chloro-1-(4-hydroxyphenyl)-2-phenyl-1-butenyl]phenyl Ester (C27H27ClO3) contains a steroid core, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 434.95 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 (E)-2,2-Dimethyl-propanoic Acid 4-[4-Chloro-1-(4-hydroxyphenyl)-2-phenyl-1-butenyl]phenyl Ester 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.
