Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-(9-((2R,3R,4S,5R)-4-((tert-Butyldimethylsilyl)oxy)-3-hydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)-9H-purin-6-yl)benzamide.

N-(9-((2R,3R,4S,5R)-4-((tert-Butyldimethylsilyl)oxy)-3-hydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)-9H-purin-6-yl)benzamide (CAS 69504-08-1), molecular formula C23H31N5O5Si and molecular weight 485.61 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, N-(9-((2R,3R,4S,5R)-4-((tert-Butyldimethylsilyl)oxy)-3-hydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)-9H-purin-6-yl)benzamide (C23H31N5O5Si) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 485.61 g/mol, it falls into the moderately-high-molecular-weight range. 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), N-(9-((2R,3R,4S,5R)-4-((tert-Butyldimethylsilyl)oxy)-3-hydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)-9H-purin-6-yl)benzamide 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.
