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 Desthiobiotin-PEG4-Alkyne.
CATO supplies Desthiobiotin-PEG4-Alkyne (CAS 1802907-99-8), a certified reference material (molecular formula C21H37N3O6, MW 427.53 g/mol) for analytical method development and quality control.
Desthiobiotin-PEG4-Alkyne (C21H37N3O6) 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), Desthiobiotin-PEG4-Alkyne 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.
