Chemical Structure

4-Cyclopropylbutanoic acid CAS 5687-84-3 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 4-Cyclopropylbutanoic acid.

4-Cyclopropylbutanoic acid (CAS 5687-84-3), molecular formula C7H12O2 and molecular weight 128.17 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-Cyclopropylbutanoic acid (C7H12O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

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.
