Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 245.23 g/mol gives 2-Chloro-4-methoxy-3-nitro-pyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Chloro-4-methoxy-3-nitro-pyridine (CAS 115396-93-5) is a high-purity analytical reference standard with the molecular formula C10H8NO3SNa and a molecular weight of 245.23 g/mol.
The molecular framework of 2-Chloro-4-methoxy-3-nitro-pyridine (C10H8NO3SNa) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-Chloro-4-methoxy-3-nitro-pyridine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
