Chemical Structure

Ethyl 2-((1aR,1bR,4aR,5aR)-3,3-dimethyltetrahydro-1aH-oxireno[2',3':3,4]cyclopenta[1,2-d][1,3]dioxol-1a-yl)acetate CAS 148811-50-1 chemical structure

Description

The occurrence of Ethyl 2-((1aR,1bR,4aR,5aR)-3,3-dimethyltetrahydro-1aH-oxireno[2',3':3,4]cyclopenta[1,2-d][1,3]dioxol-1a-yl)acetate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Ethyl 2-((1aR,1bR,4aR,5aR)-3,3-dimethyltetrahydro-1aH-oxireno[2',3':3,4]cyclopenta[1,2-d][1,3]dioxol-1a-yl)acetate (CAS 148811-50-1) is a high-purity analytical reference standard with the molecular formula C12H18O5 and a molecular weight of 242.27 g/mol.

The molecular framework of Ethyl 2-((1aR,1bR,4aR,5aR)-3,3-dimethyltetrahydro-1aH-oxireno[2',3':3,4]cyclopenta[1,2-d][1,3]dioxol-1a-yl)acetate (C12H18O5) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
