Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(3-Bromo-5-propoxyphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane.
2-(3-Bromo-5-propoxyphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 1218790-36-3), molecular formula C15H22BBrO3 and molecular weight 341.05 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-(3-Bromo-5-propoxyphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (C15H22BBrO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.5, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 341.05 g/mol, it falls into the moderately-high-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.
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.
