Di-m-tolylphosphine oxide CAS 145290-34-2

Description

Compared with other compounds in its class, the molecular weight of 230.24 g/mol gives Di-m-tolylphosphine oxide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Di-m-tolylphosphine oxide (CAS 145290-34-2), molecular formula C14H15OP and molecular weight 230.24 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to organophosphorus functionality, a hydroxyl group, an ether linkage, a polycyclic aromatic system, Di-m-tolylphosphine oxide is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 230.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), Di-m-tolylphosphine oxide 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.
