Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Bromo-2,2-difluoro-1,3-benzodioxole 5-bromo-2,2-difluoro-2h-1,3-benzodioxole 5-bromo-2,2-difluoro-benzo[1,3]dioxole 5-bromo-2,2-difluorobenzodioxole 5-bromo2,2-difluoro-1,3-benzodioxole 33070-32-5.
5-Bromo-2,2-difluoro-1,3-benzodioxole 5-bromo-2,2-difluoro-2h-1,3-benzodioxole 5-bromo-2,2-difluoro-benzo[1,3]dioxole 5-bromo-2,2-difluorobenzodioxole 5-bromo2,2-difluoro-1,3-benzodioxole 33070-32-5 (CAS 33070-32-5) is a high-purity analytical reference standard with the molecular formula C7H9BrF2O2 and a molecular weight of 243.05 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, 5-Bromo-2,2-difluoro-1,3-benzodioxole 5-bromo-2,2-difluoro-2h-1,3-benzodioxole 5-bromo-2,2-difluoro-benzo[1,3]dioxole 5-bromo-2,2-difluorobenzodioxole 5-bromo2,2-difluoro-1,3-benzodioxole 33070-32-5 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 243.05 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
