Chemical Structure

3,6-Dichloropyridazin-4-ol dihydrate CAS 1452487-57-8 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 182.99 g/mol gives 3,6-Dichloropyridazin-4-ol dihydrate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3,6-Dichloropyridazin-4-ol dihydrate (CAS 1452487-57-8), molecular formula C4H2Cl2N2OH2O and molecular weight 182.99 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 3,6-Dichloropyridazin-4-ol dihydrate is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 182.99 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
