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-[(2E)-3-(2-Chlorophenyl)prop-2-enoyl]phenyl 4-tert-butylbenzoate.
4-[(2E)-3-(2-Chlorophenyl)prop-2-enoyl]phenyl 4-tert-butylbenzoate (CAS 331461-31-5) is a high-purity analytical reference standard with the molecular formula C26H23ClO3 and a molecular weight of 418.91 g/mol.
Owing to a steroid core, a hydroxyl group, an ether linkage, chlorine substitution, 4-[(2E)-3-(2-Chlorophenyl)prop-2-enoyl]phenyl 4-tert-butylbenzoate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 418.91 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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-[(2E)-3-(2-Chlorophenyl)prop-2-enoyl]phenyl 4-tert-butylbenzoate 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.
