Chemical Structure
Description
The occurrence of H-DL-Tyr(Me)-OH 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.
H-DL-Tyr(Me)-OH (CAS 7635-29-2) is a high-purity analytical reference standard with the molecular formula C10H13NO3 and a molecular weight of 195.21 g/mol.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, H-DL-Tyr(Me)-OH is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 195.21 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-DL-Tyr(Me)-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.
