Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
2-chloro-7-methyl-9-(6-oxa-3-azabicyclo[3.1.1]heptan-3-yl)purin-8-one (CAS 2646592-60-9) is a high-purity analytical reference standard with the molecular formula C11H18ClN5O2 and a molecular weight of 287.75 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 2-chloro-7-methyl-9-(6-oxa-3-azabicyclo[3.1.1]heptan-3-yl)purin-8-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 287.75 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).
As a certified reference material (CRM), 2-chloro-7-methyl-9-(6-oxa-3-azabicyclo[3.1.1]heptan-3-yl)purin-8-one 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.
