Chemical Structure

Pbb-No. 29 CAS 115245-07-3 chemical structure

Description

The molecular framework of Pbb-No. 29 (C12H7Br3) is characterized by bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Pbb-No. 29 (CAS 115245-07-3) is a high-purity analytical reference standard with the molecular formula C12H7Br3 and a molecular weight of 390.90 g/mol.

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), Pbb-No. 29 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.
