Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies (3-Methylphenyl)oxirane (CAS 20697-03-4), a certified reference material (molecular formula C9H10O, MW 134.18 g/mol) for analytical method development and quality control.
Owing to a hydroxyl group, an ether linkage, an aromatic ring system, (3-Methylphenyl)oxirane is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 134.18 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).
As a certified reference material (CRM), (3-Methylphenyl)oxirane 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.
