Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including ((2S,3R,4R,5R)-4-acetoxy-3-azido-5-(6-benzamido-9H-purin-9-yl)tetrahydrofuran-2-yl)methyl 4-methylbenzoate.
CATO supplies ((2S,3R,4R,5R)-4-acetoxy-3-azido-5-(6-benzamido-9H-purin-9-yl)tetrahydrofuran-2-yl)methyl 4-methylbenzoate (CAS 329773-21-9), a certified reference material (molecular formula C27H24N8O6, MW 556.53 g/mol) for analytical method development and quality control.
The molecular framework of ((2S,3R,4R,5R)-4-acetoxy-3-azido-5-(6-benzamido-9H-purin-9-yl)tetrahydrofuran-2-yl)methyl 4-methylbenzoate (C27H24N8O6) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), ((2S,3R,4R,5R)-4-acetoxy-3-azido-5-(6-benzamido-9H-purin-9-yl)tetrahydrofuran-2-yl)methyl 4-methylbenzoate 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.
