2,5-dimethoxbenzoylacetonitrile 3-(2,5-dimethoxyphenyl)-3-oxopropanenitrile 898787-03-6 A10753 CAS 898787-03-6

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.

2,5-dimethoxbenzoylacetonitrile 3-(2,5-dimethoxyphenyl)-3-oxopropanenitrile 898787-03-6 A10753 (CAS 898787-03-6), molecular formula C11H11NO3 and molecular weight 205.21 g/mol, is a CATO reference standard with documented purity and traceability.

2,5-dimethoxbenzoylacetonitrile 3-(2,5-dimethoxyphenyl)-3-oxopropanenitrile 898787-03-6 A10753 (C11H11NO3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
