Chemical Structure

Freon #13b1 CAS 75-63-8 chemical structure

Description

CATO supplies Freon #13b1 (CAS 75-63-8), a certified reference material (molecular formula CBrF3, MW 148.91 g/mol) for analytical method development and quality control.

Structurally, Freon #13b1 (CBrF3) contains fluorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 0.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 148.91 g/mol, it falls into the low-molecular-weight range. 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.
