Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Tetramethyl ammonium tribromide, 98%.
Tetramethyl ammonium tribromide, 98% (CAS 15625-56-6), molecular formula Br3C4H12N and molecular weight 313.86 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Tetramethyl ammonium tribromide, 98% (Br3C4H12N) is characterized by bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing 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.
As a certified reference material (CRM), Tetramethyl ammonium tribromide, 98% 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.
