Description
8RDX889QNB 6628-86-0 5-Chloro-2-nitrobenzaldehyde EINECS 229-614-9 UNII-8RDX889QNB (CAS 6628-86-0), molecular formula C7H10ClNO3 and molecular weight 191.61 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 8RDX889QNB 6628-86-0 5-Chloro-2-nitrobenzaldehyde EINECS 229-614-9 UNII-8RDX889QNB (C7H10ClNO3) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 191.61 g/mol, it falls into the medium-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.
