Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4-(Chloromethyl)-1-methoxyheptane (CAS 1481990-37-7), molecular formula C9H19ClO and molecular weight 178.70 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4-(Chloromethyl)-1-methoxyheptane (C9H19ClO) contains a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 0.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 178.70 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.
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.
