Chemical Structure

Butyryl Chloride CAS 141-75-3 chemical structure

Description

Butyryl Chloride (CAS 141-75-3), molecular formula C4H7ClO and molecular weight 106.55 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Butyryl Chloride (C4H7ClO) contains a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 106.55 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.
