Chemical Structure
Description
CATO supplies (1R,2S)-Ethyl 2-cyanocyclopropanecarboxylate (CAS 492468-16-3), a certified reference material (molecular formula C7H9NO2, MW 139.15 g/mol) for analytical method development and quality control.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, (1R,2S)-Ethyl 2-cyanocyclopropanecarboxylate is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 139.15 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), (1R,2S)-Ethyl 2-cyanocyclopropanecarboxylate 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.
