Chemical Structure

3-Chloro-6-chloromethylpyridazine CAS 120276-59-7 chemical structure

Description

The occurrence of 3-Chloro-6-chloromethylpyridazine is closely related to a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 3-Chloro-6-chloromethylpyridazine (CAS 120276-59-7), a certified reference material (molecular formula C5H4Cl2N2, MW 163.00 g/mol) for analytical method development and quality control.

Owing to a nitrile group, chlorine substitution, 3-Chloro-6-chloromethylpyridazine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 163.00 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), 3-Chloro-6-chloromethylpyridazine 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.
