Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Meclocycline Sulfosalicylate Salt (CAS 73816-42-9), molecular formula C22H21ClN2O8C7H6O6S and molecular weight 695.04 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Meclocycline Sulfosalicylate Salt (C22H21ClN2O8C7H6O6S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 17.0, corresponding to approximately 17 ring(s) or double-bond equivalent(s). With a molecular weight of 695.04 g/mol, it falls into the high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
