Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Amino-5-deoxy-5-N-MMT-thymidine 3-CE phosphoramidite.
5-Amino-5-deoxy-5-N-MMT-thymidine 3-CE phosphoramidite (CAS 194034-71-4) is a high-purity analytical reference standard with the molecular formula C40H50N5O7P and a molecular weight of 743.83 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage, 5-Amino-5-deoxy-5-N-MMT-thymidine 3-CE phosphoramidite is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 743.83 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).
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.
CATO manufactures 5-Amino-5-deoxy-5-N-MMT-thymidine 3-CE phosphoramidite under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
