Chemical Structure

H-Thr(tBu)-OtBu CAS 5854-78-4 chemical structure

Description

H-Thr(tBu)-OtBu (CAS 5854-78-4), molecular formula C12H25NO3 and molecular weight 231.33 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, H-Thr(tBu)-OtBu is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 231.33 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), H-Thr(tBu)-OtBu 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.
