Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(4-Bromomethyl-2-thiazoyl)guanidine-13C3, Hydrobromide Salt Discontinued See: C369547.
1-(4-Bromomethyl-2-thiazoyl)guanidine-13C3, Hydrobromide Salt Discontinued See: C369547 (CAS 1329835-03-1) is a high-purity analytical reference standard with the molecular formula C2[13C]3H7BrN4S HBr and a molecular weight of 291.99 g/mol.
Based on its molecular formula C2[13C]3H7BrN4S HBr, 1-(4-Bromomethyl-2-thiazoyl)guanidine-13C3, Hydrobromide Salt Discontinued See: C369547 contains sulfur-containing functionality, bromine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 291.99 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
