Chemical Structure

2-Propenoic acid, 2-methyl-, bicyclo[2.2.1]hept-2-ylmethyl ester, polymer with butyl 2-methyl-2-propenoate CAS 66142-23-2 chemical structure

Description

The occurrence of 2-Propenoic acid, 2-methyl-, bicyclo[2.2.1]hept-2-ylmethyl ester, polymer with butyl 2-methyl-2-propenoate is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-Propenoic acid, 2-methyl-, bicyclo[2.2.1]hept-2-ylmethyl ester, polymer with butyl 2-methyl-2-propenoate (CAS 66142-23-2), molecular formula C12H18O2C8H14O2 and molecular weight 336.47 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2-Propenoic acid, 2-methyl-, bicyclo[2.2.1]hept-2-ylmethyl ester, polymer with butyl 2-methyl-2-propenoate (C12H18O2C8H14O2) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 336.47 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 2-Propenoic acid, 2-methyl-, bicyclo[2.2.1]hept-2-ylmethyl ester, polymer with butyl 2-methyl-2-propenoate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
