Chemical Structure

Testosterone Impurity 5 CAS 1099-87-2 (Anhydrous CAS) 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 Testosterone Impurity 5.

CATO supplies Testosterone Impurity 5 (CAS 1099-87-2 (Anhydrous CAS)), a pharmacopoeial impurity reference standard (molecular formula C19H27O5SNaH2O, MW 408.48 g/mol) used for the identification and quantification of trace impurities in APIs.

Testosterone Impurity 5 (C19H27O5SNaH2O) contains a steroid core, a sulfone group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.

As a certified reference material (CRM), Testosterone Impurity 5 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.
