Description
As a certified reference material (CRM), ((2-Nitrophenyl)thio)-L-threonine 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.
CATO supplies ((2-Nitrophenyl)thio)-L-threonine (CAS 7685-70-3), a certified reference material (molecular formula C23H44N2, MW 348.61 g/mol) for analytical method development and quality control.
Structurally, ((2-Nitrophenyl)thio)-L-threonine (C23H44N2) contains a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 348.61 g/mol, it falls into the moderately-high-molecular-weight range. 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.
