Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Tosyl-2-deoxy Guanosine.
5-Tosyl-2-deoxy Guanosine (CAS 109954-64-5) is a high-purity analytical reference standard with the molecular formula C17H19N5O6S and a molecular weight of 421.43 g/mol.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 5-Tosyl-2-deoxy Guanosine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 421.43 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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-Tosyl-2-deoxy Guanosine 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.
