The occurrence of 4-Bromo-1-methyl-2-phenyl-5-((pyridin-2-ylthio)methyl)-1,2-dihydro-3H-pyrazol-3-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Bromo-1-methyl-2-phenyl-5-((pyridin-2-ylthio)methyl)-1,2-dihydro-3H-pyrazol-3-one (CAS 1024324-23-9) is a high-purity analytical reference standard with the molecular formula C16H14BrN3OS and a molecular weight of 376.27 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution, 4-Bromo-1-methyl-2-phenyl-5-((pyridin-2-ylthio)methyl)-1,2-dihydro-3H-pyrazol-3-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 376.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
