Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Tert-butyl 3-(((tert-butyldimethylsilyl)oxy)methyl)-7-cyano-3-methyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)indoline-1-carboxylate.

Tert-butyl 3-(((tert-butyldimethylsilyl)oxy)methyl)-7-cyano-3-methyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)indoline-1-carboxylate (CAS 2113619-06-8) is a high-purity analytical reference standard with the molecular formula C28H45BN2O5Si and a molecular weight of 528.56 g/mol.

Tert-butyl 3-(((tert-butyldimethylsilyl)oxy)methyl)-7-cyano-3-methyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)indoline-1-carboxylate (C28H45BN2O5Si) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), Tert-butyl 3-(((tert-butyldimethylsilyl)oxy)methyl)-7-cyano-3-methyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)indoline-1-carboxylate 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.
