Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 384.30 g/mol gives Sodium tetra-p-tolylborate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Sodium tetra-p-tolylborate (CAS 15738-23-5) is a high-purity analytical reference standard with the molecular formula C27H26BNa and a molecular weight of 384.30 g/mol.
Owing to a polycyclic aromatic system, Sodium tetra-p-tolylborate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 384.30 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), Sodium tetra-p-tolylborate 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.
