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 Ethyl 5-bromo-2-hydroxy-3-methyl-4-(methylsulfanyl)benzoate.
CATO supplies Ethyl 5-bromo-2-hydroxy-3-methyl-4-(methylsulfanyl)benzoate (CAS 328288-87-5), a certified reference material (molecular formula C11H13BrO3S, MW 305.19 g/mol) for analytical method development and quality control.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, Ethyl 5-bromo-2-hydroxy-3-methyl-4-(methylsulfanyl)benzoate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 305.19 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.
