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.
CATO supplies 1,3,5,7,8-Pentamethyl-2,6-diethyl-8-phenyl-pyrromethene-difluoroborate, 97% (CAS 189264-25-3), a certified reference material (molecular formula C23H29BF2N2, MW 382.30 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution, 1,3,5,7,8-Pentamethyl-2,6-diethyl-8-phenyl-pyrromethene-difluoroborate, 97% is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 382.30 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.
CATO manufactures 1,3,5,7,8-Pentamethyl-2,6-diethyl-8-phenyl-pyrromethene-difluoroborate, 97% under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
