4-(3-Fluoro-4-methylphenyl)-2H-pyrido[2,3-e][1,2,4]thiadiazin-3(4H)-one 1,1-dioxide CAS 1325303-39-6

Description

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.

4-(3-Fluoro-4-methylphenyl)-2H-pyrido[2,3-e][1,2,4]thiadiazin-3(4H)-one 1,1-dioxide (CAS 1325303-39-6) is a high-purity analytical reference standard with the molecular formula C13H10FN3O3S and a molecular weight of 307.30 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution, 4-(3-Fluoro-4-methylphenyl)-2H-pyrido[2,3-e][1,2,4]thiadiazin-3(4H)-one 1,1-dioxide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 307.30 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).

As a certified reference material (CRM), 4-(3-Fluoro-4-methylphenyl)-2H-pyrido[2,3-e][1,2,4]thiadiazin-3(4H)-one 1,1-dioxide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
