Description
CATO manufactures Thiophene-2,5-diylbis(methylene) dicarbamimidothioate dihydrochloride 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.
Thiophene-2,5-diylbis(methylene) dicarbamimidothioate dihydrochloride (CAS 2076-91-7), molecular formula C8H12N4S3HCl and molecular weight 296.85 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Thiophene-2,5-diylbis(methylene) dicarbamimidothioate dihydrochloride (C8H12N4S3HCl) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
