Chemical Structure
Description
The occurrence of Phthalimide-3,4,5,6-d4 is closely related to deuterium isotope labeling, 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.
Phthalimide-3,4,5,6-d4 (CAS 60161-31-1) is a high-purity analytical reference standard with the molecular formula C8HD4NO2 and a molecular weight of 151.16 g/mol.
Phthalimide-3,4,5,6-d4 (C8HD4NO2) contains deuterium isotope labeling, an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
CATO manufactures Phthalimide-3,4,5,6-d4 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.
