Triphenylphosphine Oxide
Triphenylphosphine Oxide (TPPO) is an organophosphorus compound with the molecular formula C18H15OP and CAS number 791-28-6, supplied by Tianjin Security Technology Development Ltd. Co. in China. The product is offered as a research‑grade intermediate with a stated purity of at least 99 %. It appears as a white crystalline solid that is stable under typical laboratory storage conditions.
TPPO functions as a ligand precursor and extractive agent in the synthesis of pharmaceuticals, agrochemicals and fine chemicals. Its thermal stability allows it to withstand temperatures up to 250 °C without decomposition, a characteristic valued in Wittig‑type reactions. In the chemical industry, similar organophosphorus intermediates are graded as reagent‑grade (≥95 % purity) or specialty‑grade (≥99 % purity), with TPPO fitting the latter category.
The compound is purchased by contract manufacturers, research laboratories and specialty chemical formulators that require consistent reactivity. Tianjin Security Technology Development Ltd. Co. indicates flexible minimum order quantities, shipment under FOB or CIF terms, and payment via L/C or T/T. Buyers should verify the supplied certificate of analysis and confirm the applicable Incoterm before finalising the order.

Sourcing Triphenylphosphine Oxide from Tianjin Security Technology Development Ltd. Co. - China Import Guide
Before confirming a purchase, buyers should verify the supplier’s business licence and request a recent Certificate of Analysis that details purity, moisture content and any residual solvents. It is prudent to ask for the supplier’s ISO‑9001 or equivalent quality‑management certification, even if not listed, to ensure consistent production standards. Comparing the provided assay results with the typical ≥ 99 % purity benchmark helps avoid unexpected deviations.
Logistical arrangements should be clarified early, including the preferred Incoterm such as FOB Tianjin Port or CIF Shanghai, which affect freight costs and risk transfer. The supplier mentions flexible minimum order quantities, but exact lead‑time for production and dispatch must be confirmed, as it can vary with batch size and regulatory clearance. Payment options cited are Letter of Credit (L/C) and Telegraphic Transfer (T/T); confirming the acceptable documents and timelines will streamline the transaction.
Importers are advised to arrange an independent third‑party inspection before shipment, focusing on visual appearance, weight consistency and compliance with the supplied assay. Requesting a full Safety Data Sheet (SDS) and a recent batch‑wise test report will provide the necessary documentation for customs clearance and internal quality control. Aligning the inspection criteria with the typical specifications listed above ensures that the delivered TPPO meets the performance expectations of downstream synthesis processes.
