Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,1',3,3,3',3'-4,4',5,5'-Di-benzo-2,2'-indotricarbocyanine perchlorate.
1,1',3,3,3',3'-4,4',5,5'-Di-benzo-2,2'-indotricarbocyanine perchlorate (CAS 23178-67-8), molecular formula C37H37N2ClO4 and molecular weight 609.16 g/mol, is a CATO reference standard with documented purity and traceability.
1,1',3,3,3',3'-4,4',5,5'-Di-benzo-2,2'-indotricarbocyanine perchlorate (C37H37N2ClO4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 1,1',3,3,3',3'-4,4',5,5'-Di-benzo-2,2'-indotricarbocyanine perchlorate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
