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 (E)-N-(2-(3-(allylthio)-6-methyl-1,2,4-triazin-5-yl)vinyl)-O-(2,4-dichlorobenzyl)hydroxylamine.
(E)-N-(2-(3-(allylthio)-6-methyl-1,2,4-triazin-5-yl)vinyl)-O-(2,4-dichlorobenzyl)hydroxylamine (CAS 477866-16-3), molecular formula C16H16Cl2N4OS and molecular weight 383.30 g/mol, is a CATO reference standard with documented purity and traceability.
(E)-N-(2-(3-(allylthio)-6-methyl-1,2,4-triazin-5-yl)vinyl)-O-(2,4-dichlorobenzyl)hydroxylamine (C16H16Cl2N4OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
