Chemical Structure

Triethynylphosphine oxide CAS 33734-02-0 chemical structure

Description

The occurrence of Triethynylphosphine oxide is closely related to organophosphorus functionality, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Triethynylphosphine oxide (CAS 33734-02-0) is a high-purity analytical reference standard with the molecular formula C6H3OP and a molecular weight of 122.06 g/mol.

Owing to organophosphorus functionality, a hydroxyl group, an ether linkage, an aromatic ring system, Triethynylphosphine oxide is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 122.06 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), Triethynylphosphine 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.
