α,α,α′,α′-Tetrabromo-o-xylene CAS 13209-15-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including α,α,α′,α′-Tetrabromo-o-xylene.

α,α,α′,α′-Tetrabromo-o-xylene (CAS 13209-15-9) is a high-purity analytical reference standard with the molecular formula C8H12Br4 and a molecular weight of 427.80 g/mol.

Based on its molecular formula C8H12Br4, α,α,α′,α′-Tetrabromo-o-xylene contains bromine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 427.80 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), α,α,α′,α′-Tetrabromo-o-xylene 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.
