Chemical Structure
Description
5-Methoxy-2-methylbenzonitrile (CAS 22246-19-1), molecular formula C9H9NO and molecular weight 147.17 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 5-Methoxy-2-methylbenzonitrile is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 147.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 5-Methoxy-2-methylbenzonitrile 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.
