Description
58S8R4439O 563-52-0 3-Chloro-1-butene 1-Butene, 3-chloro- 3-Chlorobut-1-ene gamma-Chloro-alpha-butylene EINECS 209-252-8 alpha-Methallyl chloride alpha-Methylallyl chloride 1-Methylallyl chloride NSC 60192 UNII-58S8R4439O (CAS 563-52-0), molecular formula C4H7Cl and molecular weight 90.55 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 58S8R4439O 563-52-0 3-Chloro-1-butene 1-Butene, 3-chloro- 3-Chlorobut-1-ene gamma-Chloro-alpha-butylene EINECS 209-252-8 alpha-Methallyl chloride alpha-Methylallyl chloride 1-Methylallyl chloride NSC 60192 UNII-58S8R4439O (C4H7Cl) contains chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 90.55 g/mol, it falls into the low-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.
