Chemical Structure
Description
CATO supplies 1,1,2-Trimethyl-3-(4-sulfobutyl)benz[e]indolium Inner Salt (CAS 63149-24-6), a certified reference material (molecular formula C19H23NO3S, MW 345.46 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 1,1,2-Trimethyl-3-(4-sulfobutyl)benz[e]indolium Inner Salt is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 345.46 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 1,1,2-Trimethyl-3-(4-sulfobutyl)benz[e]indolium Inner Salt 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.
