Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Dicarboxylate of Chloramphenicol Side Chain Acid Polymer.
Dicarboxylate of Chloramphenicol Side Chain Acid Polymer (CAS CATO-C4X-232137) is a high-purity analytical reference standard with the molecular formula C31H29Cl2N5O7S and a molecular weight of 686.56 g/mol.
Structurally, Dicarboxylate of Chloramphenicol Side Chain Acid Polymer (C31H29Cl2N5O7S) 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 19.0, corresponding to approximately 19 ring(s) or double-bond equivalent(s). With a molecular weight of 686.56 g/mol, it falls into the high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
