RTI-113 CAS 141807-57-0 chemical structure

Description

As a certified reference material (CRM), RTI-113 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.

RTI-113 (CAS 141807-57-0), molecular formula C21H22ClNO2HCl and molecular weight 392.32 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, RTI-113 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 392.32 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
