Chemical Structure
Description
1, 2-(3-chloropropyl)-2-methyl- 2,2-(Ethylenedioxy)-5-chloropentane 5978-08-5 NSC-135783 NSC135783 (CAS 5978-08-5), molecular formula C7H13ClO2 and molecular weight 164.63 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1, 2-(3-chloropropyl)-2-methyl- 2,2-(Ethylenedioxy)-5-chloropentane 5978-08-5 NSC-135783 NSC135783 (C7H13ClO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
