Chemical Structure
Description
The occurrence of (R)-(-)-3-Bromo-2-methyl-1-propanol (R)-3-bromo-2-methylpropan-1-ol 93381-28-3 is closely related to a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(R)-(-)-3-Bromo-2-methyl-1-propanol (R)-3-bromo-2-methylpropan-1-ol 93381-28-3 (CAS 93381-28-3), molecular formula C4H9BrO and molecular weight 153.02 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (R)-(-)-3-Bromo-2-methyl-1-propanol (R)-3-bromo-2-methylpropan-1-ol 93381-28-3 (C4H9BrO) contains a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 0.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 153.02 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.
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.
