Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2-(Pyrrolidin-1-yl)-5-(trifluoromethyl)phenyl)boronic acid.
CATO supplies (2-(Pyrrolidin-1-yl)-5-(trifluoromethyl)phenyl)boronic acid (CAS 1704063-76-2), a certified reference material (molecular formula C11H13BF3NO2, MW 259.03 g/mol) for analytical method development and quality control.
Structurally, (2-(Pyrrolidin-1-yl)-5-(trifluoromethyl)phenyl)boronic acid (C11H13BF3NO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. 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 259.03 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
