3-Chloro-4-isopropoxyphenylboronic Acid CAS 480438-56-0

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Chloro-4-isopropoxyphenylboronic Acid.

3-Chloro-4-isopropoxyphenylboronic Acid (CAS 480438-56-0), molecular formula C9H12BClO3 and molecular weight 214.45 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 3-Chloro-4-isopropoxyphenylboronic Acid (C9H12BClO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine 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 214.45 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.

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.

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.
