Chemical Structure
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-Pyridinedi(methylchloride) (CAS 94126-97-3) is a high-purity analytical reference standard with the molecular formula C7H7Cl2N and a molecular weight of 176.04 g/mol.
Owing to a nitrile group, chlorine substitution, an aromatic ring system, 2,5-Pyridinedi(methylchloride) is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 176.04 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.
CATO manufactures 2,5-Pyridinedi(methylchloride) under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
