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 Ethyl 2-(4-(3-(trifluoromethyl)benzoyl)-3,4-dihydro-2H-benzo[b][1,4]oxazin-3-yl)acetate.
Ethyl 2-(4-(3-(trifluoromethyl)benzoyl)-3,4-dihydro-2H-benzo[b][1,4]oxazin-3-yl)acetate (CAS 439112-05-7) is a high-purity analytical reference standard with the molecular formula C20H18F3NO4 and a molecular weight of 393.36 g/mol.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, Ethyl 2-(4-(3-(trifluoromethyl)benzoyl)-3,4-dihydro-2H-benzo[b][1,4]oxazin-3-yl)acetate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 393.36 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 Ethyl 2-(4-(3-(trifluoromethyl)benzoyl)-3,4-dihydro-2H-benzo[b][1,4]oxazin-3-yl)acetate 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.
