Chemical Structure
Description
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.
(4-Chloro-phenyl)-oxo-acetaldehydeoxime (CAS 3750-07-0), molecular formula C8H6ClNO2 and molecular weight 183.59 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, (4-Chloro-phenyl)-oxo-acetaldehydeoxime is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 183.59 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.
