Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including L-Arginyl-L-arginine 7-Amido-4-methylcoumarin Trihydrochloride.
L-Arginyl-L-arginine 7-Amido-4-methylcoumarin Trihydrochloride (CAS 201847-69-0), molecular formula C22H33N9O4HCl and molecular weight 524.02 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, L-Arginyl-L-arginine 7-Amido-4-methylcoumarin Trihydrochloride (C22H33N9O4HCl) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 524.02 g/mol, it falls into the moderately-high-molecular-weight range. 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.
