Chemical Structure
Description
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.
1-Propanesulfonic acid, 3-bromo-, lithium salt (1:1) (CAS 127666-86-8) is a high-purity analytical reference standard with the molecular formula C3H6BrLiO3S and a molecular weight of 208.99 g/mol.
1-Propanesulfonic acid, 3-bromo-, lithium salt (1:1) (C3H6BrLiO3S) contains a salt form, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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.
As a certified reference material (CRM), 1-Propanesulfonic acid, 3-bromo-, lithium salt (1:1) 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.
