693-89-0 V03M1DZC9I 1-Methylcyclopentene Cyclopentene, 1-methyl- (8CI)(9CI) Cyclopentene, 1-methyl- EINECS 211-762-0 1-Methyl-1-cyclopentene NSC 64657 UNII-V03M1DZC9I (CAS 693-89-0) is a high-purity analytical reference standard with the molecular formula C6H10 and a molecular weight of 82.14 g/mol.
The molecular framework of 693-89-0 V03M1DZC9I 1-Methylcyclopentene Cyclopentene, 1-methyl- (8CI)(9CI) Cyclopentene, 1-methyl- EINECS 211-762-0 1-Methyl-1-cyclopentene NSC 64657 UNII-V03M1DZC9I (C6H10) is characterized by an organic framework. In reversed-phase chromatography, its retention is governed primarily by its non-polar molecular character, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.
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.
