Chemical Structure
Description
6-(2,4-Dimethyl-1,3-thiazol-5-yl)pyridazin-3-ol (CAS 1105195-22-9) is a high-purity analytical reference standard with the molecular formula C9H9N3OS and a molecular weight of 207.25 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 6-(2,4-Dimethyl-1,3-thiazol-5-yl)pyridazin-3-ol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 207.25 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.
As a certified reference material (CRM), 6-(2,4-Dimethyl-1,3-thiazol-5-yl)pyridazin-3-ol 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.
