Chemical Structure

1H,2H-1-Chloroperfluorocyclobutane CAS 1403667-45-7 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 1H,2H-1-Chloroperfluorocyclobutane.

1H,2H-1-Chloroperfluorocyclobutane (CAS 1403667-45-7) is a high-purity analytical reference standard with the molecular formula C4H2ClF5 and a molecular weight of 180.50 g/mol.

1H,2H-1-Chloroperfluorocyclobutane (C4H2ClF5) 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.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
