Chemical Structure

Phenylthiochloroformate CAS 1005-56-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 178.68 g/mol gives Phenylthiochloroformate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Phenylthiochloroformate (CAS 1005-56-7), molecular formula C7H11ClOS and molecular weight 178.68 g/mol, is a CATO reference standard with documented purity and traceability.

Phenylthiochloroformate (C7H11ClOS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, 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.
