5-O-tert-Butyldimethylsilyl-2,3-O-isopropylidene-D-ribose CAS 68703-51-5 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 5-O-tert-Butyldimethylsilyl-2,3-O-isopropylidene-D-ribose.

CATO supplies 5-O-tert-Butyldimethylsilyl-2,3-O-isopropylidene-D-ribose (CAS 68703-51-5), a certified reference material (molecular formula C14H28O5Si, MW 304.45 g/mol) for analytical method development and quality control.

Structurally, 5-O-tert-Butyldimethylsilyl-2,3-O-isopropylidene-D-ribose (C14H28O5Si) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 304.45 g/mol, it falls into the moderately-high-molecular-weight range.

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.
