Chemical Structure

(5-Fluoropyrimidin-4-yl)boronic acid CAS 1439366-12-7 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 (5-Fluoropyrimidin-4-yl)boronic acid.

CATO supplies (5-Fluoropyrimidin-4-yl)boronic acid (CAS 1439366-12-7), a certified reference material (molecular formula C4H4BFN2O2, MW 141.90 g/mol) for analytical method development and quality control.

Structurally, (5-Fluoropyrimidin-4-yl)boronic acid (C4H4BFN2O2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.5, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 141.90 g/mol, it falls into the low-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), (5-Fluoropyrimidin-4-yl)boronic acid 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.
