Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (4Z)-5-chloro-4,5-difluoropenta-1,4-diene 1-chloro-1,2-difluoropenta-1,4-diene 1730-23-0.

(4Z)-5-chloro-4,5-difluoropenta-1,4-diene 1-chloro-1,2-difluoropenta-1,4-diene 1730-23-0 (CAS 1730-23-0), molecular formula C5H5ClF2 and molecular weight 138.54 g/mol, is a CATO reference standard with documented purity and traceability.

(4Z)-5-chloro-4,5-difluoropenta-1,4-diene 1-chloro-1,2-difluoropenta-1,4-diene 1730-23-0 (C5H5ClF2) contains fluorine/chlorine substitution. Halogen substitution raises its density and boiling point; 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.
