Chemical Structure

α-Methyl-L-tryptophan CAS 16709-25-4 chemical structure

Description

The occurrence of α-Methyl-L-tryptophan is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

α-Methyl-L-tryptophan (CAS 16709-25-4), molecular formula C12H14N2O2 and molecular weight 218.25 g/mol, is a CATO reference standard with documented purity and traceability.

α-Methyl-L-tryptophan (C12H14N2O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

CATO manufactures α-Methyl-L-tryptophan under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
