Description
As a certified reference material (CRM), (3,4-dihydro-2H-pyrano[2,3-b]pyridin-2-yl)methanamine 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.
(3,4-dihydro-2H-pyrano[2,3-b]pyridin-2-yl)methanamine (CAS 146949-50-0) is a high-purity analytical reference standard with the molecular formula C9H12N2O and a molecular weight of 164.20 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, (3,4-dihydro-2H-pyrano[2,3-b]pyridin-2-yl)methanamine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 164.20 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.
