Chemical Structure

FR-651A CAS 87-84-3 chemical structure

Description

As a certified reference material (CRM), FR-651A 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.

FR-651A (CAS 87-84-3) is a high-purity analytical reference standard with the molecular formula C6H6Br5Cl and a molecular weight of 513.08 g/mol.

The molecular framework of FR-651A (C6H6Br5Cl) is characterized by chlorine/bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
