Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Bromo-2-pyrrolidin-1-yl-1,3-benzothiazole.
4-Bromo-2-pyrrolidin-1-yl-1,3-benzothiazole (CAS 863000-91-3) is a high-purity analytical reference standard with the molecular formula C11H11BrN2S and a molecular weight of 283.19 g/mol.
Based on its molecular formula C11H11BrN2S, 4-Bromo-2-pyrrolidin-1-yl-1,3-benzothiazole contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 283.19 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 4-Bromo-2-pyrrolidin-1-yl-1,3-benzothiazole meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
