Description
CATO manufactures (2S)-2-{[(tert-butoxy)carbonyl]amino}-2-(1-methylcyclopentyl)acetic acid 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.
(2S)-2-{[(tert-butoxy)carbonyl]amino}-2-(1-methylcyclopentyl)acetic acid (CAS 951789-87-0), molecular formula C13H23NO4 and molecular weight 257.33 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, (2S)-2-{[(tert-butoxy)carbonyl]amino}-2-(1-methylcyclopentyl)acetic acid is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 257.33 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
