DTXSID90645388 CAS 898767-43-6 chemical structure

Description

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, 898767-43-6 4-(3-Bromo-5-methylphenyl)-4-oxobutanoic acid DTXSID90645388 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 271.11 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

898767-43-6 4-(3-Bromo-5-methylphenyl)-4-oxobutanoic acid DTXSID90645388 (CAS 898767-43-6), molecular formula C11H11BrO3 and molecular weight 271.11 g/mol, is a CATO reference standard with documented purity and traceability.

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

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
