Description

(2R)-2-(9H-fluoren-9-ylmethoxycarbonylamino)-3-(4-pyridyl)propanoic acid (2R)-2-(9H-fluoren-9-ylmethoxycarbonylamino)-3-(4-pyridyl)propionic acid (2R)-2-(9H-fluoren-9-ylmethoxycarbonylamino)-3-pyridin-4-yl-propanoic acid (2R)-2-(9H-fluoren-9-ylmethoxycarbonylamino)-3-pyridin-4-ylpropanoic acid (2R)-2-[[9H-fluoren-9-ylmethoxy(oxo)methyl]amino]-3-pyridin-4-ylpropanoic acid 205528-30-9 Fmoc-D-4-Pyridylalanine (CAS 205528-30-9), molecular formula C23H38N2O4 and molecular weight 406.56 g/mol, is a CATO reference standard with documented purity and traceability.

(2R)-2-(9H-fluoren-9-ylmethoxycarbonylamino)-3-(4-pyridyl)propanoic acid (2R)-2-(9H-fluoren-9-ylmethoxycarbonylamino)-3-(4-pyridyl)propionic acid (2R)-2-(9H-fluoren-9-ylmethoxycarbonylamino)-3-pyridin-4-yl-propanoic acid (2R)-2-(9H-fluoren-9-ylmethoxycarbonylamino)-3-pyridin-4-ylpropanoic acid (2R)-2-[[9H-fluoren-9-ylmethoxy(oxo)methyl]amino]-3-pyridin-4-ylpropanoic acid 205528-30-9 Fmoc-D-4-Pyridylalanine (C23H38N2O4) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.
