Chemical Structure
Description
As a certified reference material (CRM), Isopropyl 4-bromobutanoate 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.
Isopropyl 4-bromobutanoate (CAS 70923-64-7), molecular formula C7H13BrO2 and molecular weight 209.08 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Isopropyl 4-bromobutanoate (C7H13BrO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 209.08 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.
