CATO supplies 147212-83-7 5-Ethynyl-1-(2',3',5'-tri-O-tert-butyldimethylsilyl-|A-D-ribofuranosyl)imidazo-4-carbonitrile 5-Ethynyl-1-[2,3,5-tris-O-[(1,1-dimethylethyl)dimethylsilyl]-|A-D-ribofuranosyl]-1H-imidazole-4-carbonitrile (CAS 147212-83-7), a certified reference material (molecular formula C29H53N3O4Si3, MW 592.01 g/mol) for analytical method development and quality control.

147212-83-7 5-Ethynyl-1-(2',3',5'-tri-O-tert-butyldimethylsilyl-|A-D-ribofuranosyl)imidazo-4-carbonitrile 5-Ethynyl-1-[2,3,5-tris-O-[(1,1-dimethylethyl)dimethylsilyl]-|A-D-ribofuranosyl]-1H-imidazole-4-carbonitrile (C29H53N3O4Si3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 147212-83-7 5-Ethynyl-1-(2',3',5'-tri-O-tert-butyldimethylsilyl-|A-D-ribofuranosyl)imidazo-4-carbonitrile 5-Ethynyl-1-[2,3,5-tris-O-[(1,1-dimethylethyl)dimethylsilyl]-|A-D-ribofuranosyl]-1H-imidazole-4-carbonitrile 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.
