2,2',7,7'-Tetraethynyl-9,9'-spirobifluorene CAS 1103763-99-0

Description

Compared with other compounds in its class, the molecular weight of 412.48 g/mol gives 2,2',7,7'-Tetraethynyl-9,9'-spirobifluorene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2,2',7,7'-Tetraethynyl-9,9'-spirobifluorene (CAS 1103763-99-0), a certified reference material (molecular formula C33H16, MW 412.48 g/mol) for analytical method development and quality control.

Owing to a polycyclic aromatic system, 2,2',7,7'-Tetraethynyl-9,9'-spirobifluorene is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 412.48 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), 2,2',7,7'-Tetraethynyl-9,9'-spirobifluorene 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.
