Description
CATO manufactures 2-Methylthiazole-4-carboximidamide 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.
2-Methylthiazole-4-carboximidamide hydrochloride (CAS 18876-82-9) is a high-purity analytical reference standard with the molecular formula C5H7N3SHCl and a molecular weight of 177.65 g/mol.
2-Methylthiazole-4-carboximidamide 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.
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.
