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 TBdms-peg5-1-o-(b-cyanoethyl-n,n-diisopropyl)phosphoramidite.
TBdms-peg5-1-o-(b-cyanoethyl-n,n-diisopropyl)phosphoramidite (CAS 1807521-08-9), molecular formula C23H49N2O6PSi and molecular weight 508.70 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, TBdms-peg5-1-o-(b-cyanoethyl-n,n-diisopropyl)phosphoramidite (C23H49N2O6PSi) contains an amide group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 0.5, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 508.70 g/mol, it falls into the moderately-high-molecular-weight range. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
