Chemical Structure

Cbz-L-tert-Leucine isopropylamine salt CAS 1621085-33-3 chemical structure

Description

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.

Cbz-L-tert-Leucine isopropylamine salt (CAS 1621085-33-3), molecular formula C14H19NO4C3H9N and molecular weight 324.42 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C14H19NO4C3H9N, Cbz-L-tert-Leucine isopropylamine salt contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 324.42 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
