Chemical Structure
Description
As a certified reference material (CRM), Methyl bis(bromomethyl)phosphinate 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.
Methyl bis(bromomethyl)phosphinate (CAS 885951-92-8), molecular formula C3H7Br2O2P and molecular weight 265.87 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Methyl bis(bromomethyl)phosphinate (C3H7Br2O2P) contains organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of -0.5, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 265.87 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.
