Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3-(3-Chlorobut-2-en-1-yl)-2-methylquinoline-4-thiol (CAS 61640-13-9) is a high-purity analytical reference standard with the molecular formula C14H14ClNS and a molecular weight of 263.79 g/mol.
3-(3-Chlorobut-2-en-1-yl)-2-methylquinoline-4-thiol (C14H14ClNS) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
As a certified reference material (CRM), 3-(3-Chlorobut-2-en-1-yl)-2-methylquinoline-4-thiol 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.
