Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,2-Difluorohex-5-Yne-1,4-Diamine.
2,2-Difluorohex-5-Yne-1,4-Diamine (CAS 110483-06-2), molecular formula C20H14O7 and molecular weight 366.32 g/mol, is a CATO reference standard with documented purity and traceability.
2,2-Difluorohex-5-Yne-1,4-Diamine (C20H14O7) contains 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
