Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 273.67 g/mol gives tert-Butyl (4-chloro-3-nitropyridin-2-yl)carbamate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies tert-Butyl (4-chloro-3-nitropyridin-2-yl)carbamate (CAS 1147503-86-3), a certified reference material (molecular formula C10H12ClN3O4, MW 273.67 g/mol) for analytical method development and quality control.
Structurally, tert-Butyl (4-chloro-3-nitropyridin-2-yl)carbamate (C10H12ClN3O4) 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 273.67 g/mol, it falls into the medium-molecular-weight range. 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.
