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-{[3-chloro-5-(trifluoromethyl)-2-pyridinyl]oxy}-2-(phenylsulfonyl)phenyl 4-methoxybenzenesulfonate.
4-{[3-chloro-5-(trifluoromethyl)-2-pyridinyl]oxy}-2-(phenylsulfonyl)phenyl 4-methoxybenzenesulfonate (CAS 306979-62-4) is a high-purity analytical reference standard with the molecular formula C25H17ClF3NO7S2 and a molecular weight of 599.98 g/mol.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 4-{[3-chloro-5-(trifluoromethyl)-2-pyridinyl]oxy}-2-(phenylsulfonyl)phenyl 4-methoxybenzenesulfonate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 599.98 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 4-{[3-chloro-5-(trifluoromethyl)-2-pyridinyl]oxy}-2-(phenylsulfonyl)phenyl 4-methoxybenzenesulfonate 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.
