Chemical Structure

MTH-DL-Tyrosine CAS 886-26-0 chemical structure

Description

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

MTH-DL-Tyrosine (CAS 886-26-0), molecular formula C11H12N2O2S and molecular weight 236.29 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C11H12N2O2S, MTH-DL-Tyrosine contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 236.29 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).

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.
