Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
rac Mono(5-carboxy-2-ethylpentyl) Phthalate-d4 (CAS 866864-06-4) is a high-purity analytical reference standard with the molecular formula C16H16D4O6 and a molecular weight of 312.35 g/mol.
rac Mono(5-carboxy-2-ethylpentyl) Phthalate-d4 (C16H16D4O6) contains deuterium isotope labeling, a flavonoid core, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
