151858-64-9 5-(2-pyridyl)thiophene-2-sulfonyl chloride 5-(pyridin-2-yl)thiophene-2-sulfonyl chloride 5-(pyridin-2-yl)thiophene-2-sulphonyl chloride 5-Pyrid-2-ylthiophene-2-sulfonyl chloride (CAS 151858-64-9) is a high-purity analytical reference standard with the molecular formula C9H6ClNO2S2 and a molecular weight of 259.73 g/mol.
151858-64-9 5-(2-pyridyl)thiophene-2-sulfonyl chloride 5-(pyridin-2-yl)thiophene-2-sulfonyl chloride 5-(pyridin-2-yl)thiophene-2-sulphonyl chloride 5-Pyrid-2-ylthiophene-2-sulfonyl chloride (C9H6ClNO2S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
As a certified reference material (CRM), 151858-64-9 5-(2-pyridyl)thiophene-2-sulfonyl chloride 5-(pyridin-2-yl)thiophene-2-sulfonyl chloride 5-(pyridin-2-yl)thiophene-2-sulphonyl chloride 5-Pyrid-2-ylthiophene-2-sulfonyl chloride 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.
