Description
CATO supplies 1-Chloro-9,10-bis(phenylethynyl)anthracene (CAS 41105-35-5), a certified reference material (molecular formula C30H17Cl, MW 412.91 g/mol) for analytical method development and quality control.
Structurally, 1-Chloro-9,10-bis(phenylethynyl)anthracene (C30H17Cl) contains chlorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 22.0, corresponding to approximately 22 ring(s) or double-bond equivalent(s). With a molecular weight of 412.91 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), 1-Chloro-9,10-bis(phenylethynyl)anthracene 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.
