5,5-difluoroazepane-4-carboxylic acid CAS 1334146-44-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5,5-difluoroazepane-4-carboxylic acid.

CATO supplies 5,5-difluoroazepane-4-carboxylic acid (CAS 1334146-44-9), a certified reference material (molecular formula C7H11F2NO2, MW 179.16 g/mol) for analytical method development and quality control.

5,5-difluoroazepane-4-carboxylic acid (C7H11F2NO2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
