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 Di-tert-butyl piperazine-1,3-dicarboxylate.
Di-tert-butyl piperazine-1,3-dicarboxylate (CAS 438631-75-5), molecular formula C14H26N2O4 and molecular weight 286.37 g/mol, is a CATO reference standard with documented purity and traceability.
Di-tert-butyl piperazine-1,3-dicarboxylate (C14H26N2O4) contains an amide group, a carboxylic acid 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), Di-tert-butyl piperazine-1,3-dicarboxylate 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.
