Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 229.62 g/mol gives Methyl 2-(3-chloro-5-nitrophenyl)acetate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Methyl 2-(3-chloro-5-nitrophenyl)acetate (CAS 385432-72-4), a certified reference material (molecular formula C9H8ClNO4, MW 229.62 g/mol) for analytical method development and quality control.
Structurally, Methyl 2-(3-chloro-5-nitrophenyl)acetate (C9H8ClNO4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 229.62 g/mol, it falls into the medium-molecular-weight range. 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).
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.
