Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 216.58 g/mol gives Methyl 6-chloro-3-nitropicolinate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Methyl 6-chloro-3-nitropicolinate (CAS 1805240-74-7) is a high-purity analytical reference standard with the molecular formula C7H5ClN2O4 and a molecular weight of 216.58 g/mol.
Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, Methyl 6-chloro-3-nitropicolinate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 216.58 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
