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.
CATO supplies 4-Methyl-2,3,4,5-tetrahydrobenzo[f][1,4]oxazepine-7-carboxylic acid (CAS 933703-66-3), a certified reference material (molecular formula C11H13NO3, MW 207.23 g/mol) for analytical method development and quality control.
The molecular framework of 4-Methyl-2,3,4,5-tetrahydrobenzo[f][1,4]oxazepine-7-carboxylic acid (C11H13NO3) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
