Chemical Structure

8-methyl-5H-pyridazino[4,5-b]indole-4-thiol CAS 950094-55-0 chemical structure

Description

CATO supplies 8-methyl-5H-pyridazino[4,5-b]indole-4-thiol (CAS 950094-55-0), a certified reference material (molecular formula C11H21N3S, MW 227.37 g/mol) for analytical method development and quality control.

8-methyl-5H-pyridazino[4,5-b]indole-4-thiol (C11H21N3S) contains a nitrile group, sulfur-containing functionality. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 8-methyl-5H-pyridazino[4,5-b]indole-4-thiol 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.
