Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-[13-(3,4-Dichlorophenyl)-11,12-dimethyl-4,6,10-trioxatricyclo[7.4.0.0^{3,7}]trideca-1(9),2,7-trien-11-yl]pyrrolidine.
1-[13-(3,4-Dichlorophenyl)-11,12-dimethyl-4,6,10-trioxatricyclo[7.4.0.0^{3,7}]trideca-1(9),2,7-trien-11-yl]pyrrolidine (CAS 1005106-24-0), molecular formula C22H23Cl2NO3 and molecular weight 420.33 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-[13-(3,4-Dichlorophenyl)-11,12-dimethyl-4,6,10-trioxatricyclo[7.4.0.0^{3,7}]trideca-1(9),2,7-trien-11-yl]pyrrolidine (C22H23Cl2NO3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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-[13-(3,4-Dichlorophenyl)-11,12-dimethyl-4,6,10-trioxatricyclo[7.4.0.0^{3,7}]trideca-1(9),2,7-trien-11-yl]pyrrolidine 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.
