Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including tert-Butyl (7'-methyl-5'-oxo-5',7'-dihydrospiro[cyclopropane-1,8'-pyrano[4,3-b]pyridin]-2'-yl)carbamate.
tert-Butyl (7'-methyl-5'-oxo-5',7'-dihydrospiro[cyclopropane-1,8'-pyrano[4,3-b]pyridin]-2'-yl)carbamate (CAS 2673370-73-3) is a high-purity analytical reference standard with the molecular formula C16H20N2O4 and a molecular weight of 304.34 g/mol.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, tert-Butyl (7'-methyl-5'-oxo-5',7'-dihydrospiro[cyclopropane-1,8'-pyrano[4,3-b]pyridin]-2'-yl)carbamate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 304.34 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), tert-Butyl (7'-methyl-5'-oxo-5',7'-dihydrospiro[cyclopropane-1,8'-pyrano[4,3-b]pyridin]-2'-yl)carbamate 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.
