Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-cyclopropyl-1,3,4-thiadiazol-2-amine hydrochloride.
5-cyclopropyl-1,3,4-thiadiazol-2-amine hydrochloride (CAS 857748-65-3), molecular formula C5H7N3SHCl and molecular weight 177.65 g/mol, is a CATO reference standard with documented purity and traceability.
5-cyclopropyl-1,3,4-thiadiazol-2-amine hydrochloride (C5H7N3SHCl) contains a nitrile group, sulfur-containing functionality, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 5-cyclopropyl-1,3,4-thiadiazol-2-amine hydrochloride 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.
