Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (S)-7-Bromo-1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid.
(S)-7-Bromo-1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid (CAS 77141-10-7), molecular formula C10H10BrNO2 and molecular weight 256.10 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C10H10BrNO2, (S)-7-Bromo-1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 256.10 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.
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.
