Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-Methyl-1H-imidazole-5-thiol.
CATO supplies 1-Methyl-1H-imidazole-5-thiol (CAS 184590-93-0), a certified reference material (molecular formula C4H6N2S, MW 114.17 g/mol) for analytical method development and quality control.
Owing to a nitrile group, sulfur-containing functionality, 1-Methyl-1H-imidazole-5-thiol is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 114.17 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.
CATO manufactures 1-Methyl-1H-imidazole-5-thiol 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.
