Chemical Structure
Description
The occurrence of Cyclopropanecarbonyl isothiocyanate is closely related to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Cyclopropanecarbonyl isothiocyanate (CAS 171058-80-3), a certified reference material (molecular formula C5H5NOS, MW 127.16 g/mol) for analytical method development and quality control.
Owing to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, Cyclopropanecarbonyl isothiocyanate is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 127.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Cyclopropanecarbonyl isothiocyanate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
