Chemical Structure
Description
As a certified reference material (CRM), 2-Bromo-3-methylsuccinic acid 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.
2-Bromo-3-methylsuccinic acid (CAS 7405-17-6), molecular formula C5H7BrO4 and molecular weight 211.01 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-Bromo-3-methylsuccinic acid (C5H7BrO4) contains a carbohydrate-derived structure, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 211.01 g/mol, it falls into the medium-molecular-weight range. 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.
