Butanedioic acid, bromo-, dimethyl ester, (R)- CAS 99147-12-3

Description

Compared with other compounds in its class, the molecular weight of 225.04 g/mol gives Butanedioic acid, bromo-, dimethyl ester, (R)- distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Butanedioic acid, bromo-, dimethyl ester, (R)- (CAS 99147-12-3), molecular formula C6H9BrO4 and molecular weight 225.04 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Butanedioic acid, bromo-, dimethyl ester, (R)- (C6H9BrO4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional 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.

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.
