Chemical Structure

Ac-D-Cys(Trt)-OH CAS 1998701-33-9 chemical structure

Description

Ac-D-Cys(Trt)-OH (CAS 1998701-33-9) is a high-purity analytical reference standard with the molecular formula C24H23NO3S and a molecular weight of 405.51 g/mol.

Structurally, Ac-D-Cys(Trt)-OH (C24H23NO3S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 405.51 g/mol, it falls into the moderately-high-molecular-weight range. 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).

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), Ac-D-Cys(Trt)-OH 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.
