Chemical Structure
Description
Trans-3＇-Hydroxy Cotinine-d3 (Racemic Mixture) (CAS 159956-78-2), molecular formula C10H9D3N2O2 and molecular weight 195.23 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to deuterium isotope labeling, an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, Trans-3＇-Hydroxy Cotinine-d3 (Racemic Mixture) is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 195.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), Trans-3＇-Hydroxy Cotinine-d3 (Racemic Mixture) 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.
