Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Amino-2-bromo-5-methylthiazole Hydrobromide.
CATO supplies 4-Amino-2-bromo-5-methylthiazole Hydrobromide (CAS 70346-22-4), a certified reference material (molecular formula C4H5BrN2SHBr, MW 273.97 g/mol) for analytical method development and quality control.
Owing to a nitrile group, sulfur-containing functionality, bromine substitution, 4-Amino-2-bromo-5-methylthiazole Hydrobromide is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 273.97 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
CATO manufactures 4-Amino-2-bromo-5-methylthiazole Hydrobromide 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.
