Explore ester structures, synthesis from the standpoint of chemistry, biology, and nursing students studying lipids and functional groups, and hydrolysis for only $17.00.
Understanding esters & their linkage is essential for both organic chemistry and biochemistry students. Indigo® Orbit molecular models provide a clear & intuitive physical representation of the characteristic (-COOR) functional group. Ester molecular models highlight the spatial relationship between the carbonyl group and the adjacent ether-linked oxygen. Assembling different configurations allows students to move from abstract 2D drawings to mastering IUPAC nomenclature rules, recognize stereo-hindrance, and compare & contrast esters with closely related carboxylic acids, ethers, and anhydrides.

| Compound | Chemistry Focus | Biology / Medicine / Nursing Focus |
|---|---|---|
| Ethyl Acetate | Classic product of Fischer esterification; models an aliphatic ester with distinct volatility and low polarity ideal for solvent extractions. | Naturally occurring compound in ripening fruits; widely used to teach environmental flavor chemistry and sensory analysis. |
| Methyl Salicylate | Aromatic ester showcasing how an ester link interfaces with a benzene ring; models base/acid-catalyzed cleavage mechanisms. | Found in oil of wintergreen; central to pharmacology studies regarding topical analgesics, absorption barriers, and counter-irritants. |
| Isoamyl Acetate | Models a branched-chain ester; excellent for tracking structural chain-length variations and spatial geometric constraints. | Renowned for its strong banana aroma; frequently utilized in sensory biology laboratories to demonstrate olfactory receptor binding. |
| Triglyceride | Models a massive triester structure; visualizes spatial constraints, hydrophobic interactions, and multi-step saponification properties. | Primary form of lipid energy storage in organisms; critical for teaching dietary nutrition, cardiovascular health, and clinical lipid disorders. |
Aspirin (Acetylsalicylic Acid) |
Illustrates functional acetylation chemistry; physical models track how the ester bond destabilizes and hydrolyzes back to salicylic acid. | Ubiquitous NSAID and antiplatelet drug; vital for clinical nursing and medical education covering toxicology, metabolism, and bleeding risks. |
| Polyester (PET) | Demonstrates macro-scale polymer construction where repeating ester sequences form durable synthetic fibers. | Essential for biotechnology, biomedical material engineering, and understanding the persistence of microplastics in eco-systems. |
Use the 68845NV Organic Chemistry Model Set with the Indigo® Instruments 3D Molecular Model Builder to view hundreds of ester structures & the parts needed to build them.
I've had consistently great service from this company. Our students seem to really appreciate the reasonable price. In the years that we've used this product, not one has been returned due to defects.
Considering how many of these we sell to schools every year, that is high praise indeed. Thanks letting us know.
The easiest way to view & then build esters with this model set is to use our 3D Molecular Model Builder in Orbit (basic) style. Just enter the compound name, hit the Build & Show Purchase options button & an image of the molecule & parts needed will appear. Follow the same steps but choose Orbit (flexible) to view Esters; Advanced Ochem set.
Yes, the Orbit molecular model system allows for scaling. Unlike the Darling rigid framework style with its fixed bond lengths, the Indigo® 68845NV student molecular model set comes with 121 bonds across three standard lengths (20mm, 30mm, and 35mm). The flexible white and grey bonds can be cleanly cut with a single edge razor or x-acto blade. Advanced chemistry majors can scale these bonds to match varying atomic radii. This allows for analysis of real-world steric hindrance differences between compact aliphatic esters like ethyl acetate and bulky ring-structured aromatic esters like methyl salicylate.
