Chemical Structure

(S)-(-)-SEGPHOS® CAS 210169-54-3 chemical structure

Description

Owing to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, (S)-(-)-SEGPHOS® is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 610.57 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

(S)-(-)-SEGPHOS® (CAS 210169-54-3) is a high-purity analytical reference standard with the molecular formula C38H28O4P2 and a molecular weight of 610.57 g/mol.

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), (S)-(-)-SEGPHOS® 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.
