Chemical Structure

Triisobutylphosphine Sulphide CAS 3982-87-4 chemical structure

Description

Owing to sulfur-containing functionality, organophosphorus functionality, Triisobutylphosphine Sulphide is typically white to off-white low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 234.38 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.

Triisobutylphosphine Sulphide (CAS 3982-87-4), molecular formula C12H27PS and molecular weight 234.38 g/mol, is a CATO reference standard with documented purity and traceability.

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), Triisobutylphosphine Sulphide 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.
