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 1,5-Bis(4-amidinophenoxy)-3-pentanol.
1,5-Bis(4-amidinophenoxy)-3-pentanol (CAS 133991-33-0) is a high-purity analytical reference standard with the molecular formula C19H24N4O3 and a molecular weight of 356.42 g/mol.
The molecular framework of 1,5-Bis(4-amidinophenoxy)-3-pentanol (C19H24N4O3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), 1,5-Bis(4-amidinophenoxy)-3-pentanol 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.
